Partially redeeming a Casascius physical bitcoin - help request

Overview of problem
I have a Casascius physical bitcoin and I am unable to add its digital contents to a wallet. It seems that the key is not the right length or format. I started to get out of my depth with talk of things like a Minikey format.
I removed the hologram when I was given it years ago as I was curious what was under there. I don't want to sell it instead I want to add its 1 BTC value to a wallet so I can partially redeem it and keep the physical brass as a collectible.
What I have observed and tried (apologies in advance for butchering terms)
I've searched several sites, including here and haven't been able to find a current answer for the new style of keys and wallets.
I put the seven character code from the hologram into the casascius.uberbills dot com site and it gives me a 33 character key, tells me it's version 2 and confirms that it has a 1 BTC value
I've tried to import it into a Blockchain wallet but get the error "this private key does not match the watch only address above" when I enter the private key under the hologram. For some reason it seems like a different public address is generated when I enter the 33 char code.
I tried to import it into a Jaxx Liberty wallet but it doesn't recognise the minikey or 33 char code as valid.
I've basically run up against my level of knowledge and don't know what the next steps are of if I'm missing something bleeding obvious. I double and triple checked any data entry because I saw this was a common problem.
I'd really appreciate any help or pointers the community can give me.
Thanks
Edit:
Solution
I followed the advice given by u/murbul in reply to my post
You might struggle to find a wallet that natively supports MINI keys these days since it's an old format that never really took off apart from Casascius coins. So your best bet is to use a tool to convert it to a real private key (starting with 5) and import/sweep that into a wallet.
You can convert it on the Wallet Details tab of https://www.bitaddress.org/ - For 1 BTC I'd be paranoid enough to recommend downloading the source and doing everything offline: https://github.com/pointbiz/bitaddress.org
I used the site and one of the keys generated was one starting with '5' (Private Key WIF). I used this in Jaxx Liberty in the 'Paper Wallet Import' function under tools and it came right across.
I’m very happy.

Could you build a wallet that simply sends a private key, bypassing all transaction time & costs?

The wallet would store btc in multiple addresses in reasonably small units, and then simply send over the private key via a secure protocol. The recipient then becomes the de facto owner without ever performing a transaction on the ledger.

Basic Bitcoin security guide

Hello,
This post is to give you a quick introduction into Bitcoin security. While nobody can guarantee you 100% security, I hope to mitigate some problems you can run into. This is the “20% of effort to get you to 80% safe”.
First of all, you have to determine how much money you want to hold in Bitcoin and how much effort are you willing to put in. If you are happy just holding a few dollars worth and don’t care if you lose them, that’s one approach to take. For everyone else, lets get started.
Password strength
A lot of the times how secure your money is will be determined by the strength of your password. Since in the worst case scenario we are talking about someone trying to brute force your wallet, casual online passwords are too weak. Under 10 characters is too weak. Common words and phrases are too weak. Adding one number to a password at the end is too weak.
Moreover, you can consider your password much weaker if you:
If you want a really strong password:
Wallet security
Now we are getting to the meat of things.
There are a number of wallets available to store your hard earned bitcoins. If you have a decent amount of coins to store, you should look into software wallets - BitcoinQT, MultiBit, Armory or Electrum. They are among the best place to store your money safely (provided your computer is secure as well). Chose one you think best suits you, install it and encrypt your wallet file with your strong password. You should take your wallet file and back it up (location of the file is different for different clients, so you have to do some research as to where to find that file). Back it up on a CD, safe USB drive or the like. Keep them safe. If you lose that file, you will lose your money.
A quick word on deterministic wallets. Electrum and Armory allow you to create wallets from a seed. If you use the same seed later, you can recreate your wallet on other machines. With deterministic wallets, you only need to keep that seed secure to have access to your money.
In comparison, in BitcoinQT's traditional wallet, every address you use is random, meaning that after you send 50-100 outgoing transactions your backups can be obsolete. Always keep an up-to-date backup of such wallet file if possible.
Okay, sometimes you need to have your Bitcoins with you when you leave your computer. In this case, you should look into either online or mobile wallets. A staple for both of those is Blockchain.info, but there are others to chose from.
A good rule of thumb with these is to not store more money in them than you can afford to lose. They are best used as a convenient way of accessing some money, not storing your savings. Online wallets are especially vulnerable to their servers getting hacked and people’s money getting stolen.
What to keep in mind while using online wallets:
  • Use a secure password (the more money you have in them the stronger the password should be)
  • Always keep a backup of your wallet in case you need to recover your money
  • Whenever possible, enable two factor authentication
  • Don’t use your online wallets from unsafe computers
Cold storage
Sometimes you want to store your bitcoins for a long time in a safe place. This is called “cold storage”. There are a few ways one can do this.
First of all, paper wallets. They are nice for giving people small bitcoin gifts, but also for long-term storage if properly used. What you want to do is generate and print them offline. You can save the linked page for example and run that offline. If you are really paranoid, you can put it on read-only media and access that from a different computer. For really long term storage, use archival-grade paper.
Another approach to take is using a separate computer for storing your money that is offline 99+% of the time. You could set one up easily by buying an old laptop, reformatting it, installing Linux and a Bitcoin client. Generate an address on that machine and send money to it from your main wallet. Depending on how paranoid you are you can connect that computer to the Internet afterwards to synchronize data with the Bitcoin Network and then turn it off and put it away somewhere safe until it’s needed.
Brain wallets
Don’t. They are not for you. Unless you are a security-conscientious programmer, those are not for you.
Diversifying
Keeping all of your eggs in one basket is never a good thing. You should look into diversifying some of your Bitcoin assets in case your other storage methods fail. Some ways you can diversify:
  • Buy a physical Bitcoin. As long as you trust the coin creator such coins can be an effective cold storage
  • Invest - I wouldn’t recommend this for more than some trivial amount unless you know what you are doing, but investing in some Bitcoin stocks could be a way to get more money out of your bitcoins
How not to diversify:
  • Avoid keeping your bitcoins at exchanges or other online sites that are not your online wallets. Such sites can be closed down or disappear along with your money.
  • Alt-coins - there are few cryptocurrencies that are worthwhile, but most of them are just Bitcoin clones. If a currency brings nothing new, it’s worthless in comparison to Bitcoin. Namecoin is a distributed domain name server (although recently it had a fatal flaw uncovered, so be warned), Ripple is a distributed currency exchange and payment system. Litecoin will only be useful in case Bitcoin’s hashing algorithm gets compromised (very unlikely at this time). Beyond that there are few if any alt-coins that are a worthwhile way of diversifying.
Accepting payments and safety
We’ve covered safe ways to store money, now a quick note about bitcoin payments and their safety.
First of all, when you are sending a transaction, pay your fees. Transactions without fees can take forever to propagate, confirm and clear. This can cause you a lot of stress, so pay your fees.
Secondly, when accepting large Bitcoin payments (say you want to suddenly cash in a gold bar into bitcoins), wait for at the very least 1 confirmation on those transactions. 6 is best, but having even 1 confirmations is a lot better than having none. This is mainly a rule of thumb for the paranoid (I wouldn’t be doing this for most casual transaction), but maybe it will save you if you are dealing with some shady people.
Wrapping up...
That should cover the basics. If you want to read more about Bitcoin’s security in general, here is my master thesis on the subject. A lot of questions about Bitcoin and security have also been answered on Bitcoin StackExchange - be sure to check it out.
Comments and improvement suggestions welcome.

Hi Departments of Financial Services, Here is the proposed Virtual Currency Regulator Application

In developing this regulatory framework, we have sought to strike an appropriate balance that helps protect individuals, consumers, businesses, services, and innovators, while rooting out unscrupulous and over-reaching regulatory activity. These regulations include provisions to help safeguard customer assets, protect against unwarranted account freezes or seizures, and prevent the regulatory abuse of virtual currencies from unethical activity, such as widespread warrantless monitoring, disclosure of private information, dictation as to how users engaged in P2P or non-fiat transfers can spend their money, and scapegoating.
We recognize that not everyone in the regulatory community will be pleased about the prospect of what could be seen as a barrier to their regulatory authority. Ultimately, though, we believe that setting up common sense rules of the road is vital to the long-term future of the virtual currency industry, as well as the safety and soundness of customer assets. (We think the situation in New York, for example, made that very clear.) Moreover, given that P2P decentralized networks are stateless, headless, community consensus driven bodies, we also have a moral obligation to move forward on this framework.
Entities are considered "interested in regulating virtual currencies" if:
... in a manner that would affect any current or prospective member of the human race.
Entities "interested in regulating virtual currencies" must:
As the first decentralized community to put forward specially tailored rules for virtual currency regulators – continued public feedback will be an important part of finalizing this regulatory framework. We look forward to carefully and thoughtfully reviewing public comments on our proposal.

'What's wrong with my current cold storage method?' - an examination of potential weaknesses in the most common cold storage methods

Today we are going to discuss cold storage and some specific problems with cold storage. While this applies directly to the Secret Key portion of a key-pair; it also applies to the seed used to back up HD wallets and hardware wallets.
The best way to keep you seed/secret key safe is to have multiple copies in multiple locations perhaps with multiple formats and even better if the keys are split. However not everyone has access to multiple locations, or access to land long term, or more than one place to store their things. This is an examination of faults with individual methods; and not a comprehensive plan, obviously.
Not to say everything is all bad but there are many potential weakness out there, and some in the Bitcoin and crypto community like to know the edge cases of things.
I will also highlight some of the aspects of the Keyois Capsule which is a 'physical bitcoin'.
A physical Bitcoin is a cryptographic key pair, a physical key printed and affixed to what has always been before a coin. The first physical bitcoin coin was the Casascius coin, since then the world of physical bitcoin coins has blossomed as a fun part of the Bitcoin world.
We will focus on mediums relating to cold storage and not ones designed for more everyday use, but this applies to the seed you save to keep your everyday spending wallets safe and backed up.
We will assume you generated your keys securely and that you already have them on some medium. We will also have to ignore endpoint physical security because they can all be carried away the same. Remember your cell phone /hardware wallet/ computer client are only as good as where you put the backup seed phrase, which can be thought of as data much like the SK discussed below.
Written on a piece of paper
Printed on a piece of paper
On laminated paper
Engraved / etched/ ablated/ stamped on a piece of metal
Stored digitally on a computer
Stored digitally on CD, floppy disk, laserdisc, or mini-disc
Stored digitally on a flash drive
Backups are essential for digital data Computer code for performing operations can be corrupted in transfer or in operation. Special systems exist and procedures help data to last longer. For ideas, see this archive.gov page Remember to store in multiple locations. You can lose everything in single structure
A physical bitcoin coin
**What can solve most of these problems? A combination of good backup procedures and encryption. **
If you have permeant access to more than one location (people who live in big cities, without family or cars have a hard time with this) or have people you trust with your money (don't) then look into using some form of Multi-signature option.
The Keyois Capsule is a crypto piggy bank; it can be funded from the outside but you to break it open to get them out. You give me a BIP38 encrypted key pair (well the address not the public key) and I engrave it in this tamper evident and time resistant package. You still have to hold on to the pass phrase that allows you to decrypt it; that is however the same problem as all methods with BIP38 encryption. How to store this without having to trust anyone but still being assured of it's security?
  • Engraving, embossing, or stamping on a sheet of metal is one option; however the metals that are easiest to stamp are ones that melt in a house fire. They could be put in a glass jar that's filled with aerogel and buried. These is the best readily available option for most people but it really can be tedious. - This puts you back at anyone who can see it can steal it so dip in plastic dip, wrap in duct tape, bake in clay, encase in concrete, whatever just don't leave unencrypted keys visible!
  • The cryptosteel is another ready-made option
  • Have the words etched onto glass at home with off the shelf products; but be carful of this idea because the glass can shatter from impact and heat or even sudden temperature changes
  • Anodize the words yourself on a pieces of metal, there used to be a service to help use your home printer to print the words with some chemicals you can buy
  • Bake them in clay, then encase that in epoxy resin so it can't shatter. then paint the outside, in the future you can solvent the paint off and see the written seed
  • Use a combination of techniques to split the seed so that it is safe(because split and separated) and redundant (because backed up).
The most cost effective way for a 'normal' person (without their own land, without more than one location, and who cannot trust anyone else with their funds) to keep their backup seed/ secret key safe from damage from the elements would probably to buy a stamping kit and hammer and some stainless steel sheet or bar, Aluminium can be okay if you have the right alloy but better safe than sorry.

An Ark: Bitcoin marketplace with trust-free escrow

Hi Reddit!

Introduction

We all know that we should never trust bitcoins to sites with hotwallets, but up until now there has not been a good way to do trades without one. Multi-sig promises to deliver trust-free escrow, but so far it has been difficult to make widely accessible due to wallet fragmentation and a confusing user experience.
After doing some research, I discovered that we could make a much more user-friendly system that is functional today while still achieving trust-free escrow similar to multi-sig. The alternate method we are using is called the Casascius Escrow Scheme and it was invented by Mike Caldwell. You can read about it here: https://en.bitcoin.it/wiki/User:Casascius/Escrow_scheme_draft It is similar to Shamir's secret sharing, but it was specifically designed for escrow. The javascript implementation can be found at www.bitescrow.org (this is what I used).
Using this scheme we are able to perform escrow functions (like refunds) while never actually touching the bitcoins. There is no hot-wallet, meaning funds cannot be lost or stolen from our servers. Keys are generated separately in each user's browser and on the server in a way that prevents the server from ever having all the keys needed to spend the bitcoins. In fact, once the seller accepts a purchase request, the entire transaction can be completed offline by manually exchanging escrow codes with the other party.
This method is trustfree because all the important code is client-side and can be reviewed. Additionally, all the HTTP requests can be examined to ensure there is no sensitive data being passed to the server.

Pros and Cons

The major limitation of this method is that partial refunds from escrow are not possible, the escrow address is winner-take-all fund. Also, the transaction types cannot be very complex.
On the other hand, there's no sending long and confusing blocks of text back and forth to be deciphered and signed. There's no worrying about how to publish your transaction to the bitcoin network, and there's no waiting for confirms. You can load the private key into your wallet (wif) and see the funds immediately.

Usage

So we went ahead and created a basic market place around this escrow system. Making an account is as easy as signing up with an email. The email you sign up with WILL BE SHARED with users you contact, or users who request to purchase your listing. For security reasons, we do not want to handle user communications at this time. We want to focus on providing the most secure marketplace and would encourage you to find alternate channels of communication beyond email if needed.
Every time you create or accept a transaction, you must make an Escrow Transaction Password. This password protects the sensitive bits of the transaction from the server, meaning if you lose it you will have to release the escrow funds to the other party. If both people lose it, the funds in the escrow address will be lost.
Right now we are looking for feedback and have made no decisions about account limits or pricing. Currently the system is 100% free to use. Please let us know your thoughts! If you have any questions, concerns, or ideas just reply to this thread or email [email protected] and I will get back to you asap.

Selling some Physical Bitcoins & other cryptos! Fair Prices!

Verification and More Pictures
Pictures of Lealana Brass, I forgot to add some to the main album
Hey guys, I have a huge collection of physical Bitcoins & other physical cryptos, and I'm selling a few extras just to be able to buy 1 or more coins still on my "Wish List." I love all coins in general, but these are my favorite to collect followed by old world silver coinage & Norfed Liberty Dollars. I haven't sold much on Reddit yet, but I have a 100% positive feedback eBay account and also a lot of positive trust feedback on Bitcointalk.org.
eBay Account and BitcoinTalk profile (click on "trust" to see feedback)
Added some brief information about the coins in italics
For Sale:
MicroSoul's original coins were minted in the UK. Low mintage, but not sure off the top of my head what the numbers were. They released a couple series and some in .999 fine silver.
These coins came from Crypto Imperator in Spain. They have released these 10,000 Dogecoins made of brass- total mintage of 500, and did a limited run of only 25 coins in .999 fine silver containing it's face value of 100,000 Dogecoins, and are currently working on a run of only 10 .999 fine gold 1,000,000 Dogecoins. There are 5 left of 10, check here for more info. They also made 1 physical Bitcoin, all are very finely made beautiful coins. CI's coins are in no way related to the Silver bullion Dogecoin coins you may have seen.
bhcoins come from a pair in Argentina. They have released 4 different series in the past few years. These coins are from Series 3 and a mintage of only 200, with the first 20 reserved by the creators.
Cryptolator is based in Canada but minted at the esteemed Northwest Territorial Mint in Washington state. Their only design so far was the Unchained Series, minted in .999 fine silver, copper, Merlin Gold, antique copper, and antique brass. These copper coins listed are from a limited mintage of 500. The the coin is minted with proof-like quality and features the "Unchained Series" design, according to the maker: "The artist's design on the face of the coin represents us breaking free from the "chains that bind us" to the banks. In front of the bank, there is a pig and a dog sitting (the pig representing a banker & the dog a businessman), and the people running from the collapsing bank are considered as the sheep that are freeing themselves. This is a reference to the Pink Floyd album, Animals. The crying eye at the top of the bank is the Illuminati eye that is now closed and crying, the sad "pig" bankers who have lost from the liberating peer-to-peer money system that is Bitcoin."
Lealana is based in Hawaii but these coins were minted at the Northwest Territorial mint in Washington state. They are most known for their Lealana Litecoins, which were minted in silver and early followers after the trailblazing Casascius Bitcoins
These Lealana coins are the "Buyer Funded" model, and do not contain or come with any digital Bitcoin value, but any amount of Bitcoin can be loaded onto them for cold storage. They have a unique Bitcoin address assigned to them with private key inside. In this case the denomination or face value of 0.1 Bitcoin is just a suggestion; any amount of BTC can be sent to the coins
All coins are in mint condition (have never been handled) or the condition they were in coming from their maker. Not really in any hurry to sell these coins and don't need the money, so probably won't come down a ton on price, but can negotiate discounts if buying a few. I feel like these prices are pretty fair based off of current and past sales of similar coins.
Payment Info:
Will take payment in Bitcoin or PayPal Friends & Family (leave note line blank), and/or will accept PayPal G&S +3% from trusted members with positive feedback.
Shipping Info:
Free standard tracked shipping for US residents (this will be a small bubble mailer with First Class postage) or you can add $3 and I will bump you up to 2-Day Priority with a Small Flat Rate Box.
Willing to ship nearly anywhere in the world. I will always try to ship for as fair a price as possible, so if you're outside the US and want to buy, ask for a quote and I will see what options we have.
Will Ship Same Day Payment is Received 99% of the Time!
Any Questions Just Ask! Thanks
About Physical Bitcoins/other cryptos:
In 2011 a man named Mike Caldwell, an avid supporter of cryptography and Bitcoin, had an idea to mint physical coins that could represent digital Bitcoin value in a more conventional way, so that more people would be able to conceptualize and understand this new digital cryptocurrency technology. He came up with a way to mint a physical coin that actually contained the digital Bitcoin value it represented. On one side of the coin, he had a recessed groove stamped into it. He then securely and safely generated new Bitcoin address public & private keys, printing the private keys (needed to spend the funds) and placing them in the recessed groove. He then had complex & layered tamper-evident holograms created to cover the private key, which served 2 purposes: 1- these complex holograms made it harder to ever create a believable counterfeit of his coins, and 2- when the holograms were peeled back exposing the private key needed to spend the funds, it left a honeycomb pattern behind, which would instantly tell someone considering buying one on the 2nd market whether the coin still contained its valuable BTC funds, or if it had been spent. He called his coins Casascius physical Bitcoins, and they proved to be very popular, with several different denominations and Series released over a couple years' time. Today these coins are highly valued & sought after collectors' items. Many individuals, groups, and companies followed suit in the years that followed, designing and minting their own physical crypto coins. And that's where we are today with these coins I have for sale. :) I tried my best to explain how physical Bitcoins work in a limited space, but it is hard to fully summarize such a topic in so few words, so if you have any questions just ask!

Want some personalized vanity addresses for your currency of choice? Check out Vanity Pool

I run a small project called Vanity Pool, it lets you outsource generation of cool vanity addresses through a split-key address algorithm - this means that your private key and thus your money is secure, even though other people mined for your address. This also means that you can get some nice vanity addresses and not have to spend a lot of your GPU time mining for the address instead of mining for your coin of choice.
So if you want some cool vanity address, like DDogeWowAA2EFcGmipzDjQBYQFXiqC8QFs or 1PiachuEVn6sh52Ez7o6Fymvw54qvQ4RBm , head on over to https://vanitypool.appspot.com/ , request a pattern you wish created (shorter patterns area cheaper and take a lot less time to generate), put in a public key that you own (you will need to use it later), when asked for network prefix, put in the decimal version of your coin-specific net-byte. Afterwards, you will be requested to pay a bounty in BTC (creating coin-specific pool would make the mining power a lot smaller; miners prefer being paid in BTC). After the payment is confirmed, any miner connected to the pool will start looking for the solution to your pattern.
Once you have the solution, either use Casascius' Address Utility, or head on over to our online tool (use coin-specific hex NetByte and hex Prefix Byte). After that you can import your new vanity address to your client by going through those steps (example using Dogecoin client).
Have fun!

Hey guys, I have a huge collection of physical Bitcoins & other physical cryptos (such as these physical Dogecoins), and I'm selling a few extras. I love all coins in general, but these are my favorite to collect closely followed by old world silver coinage & Norfed Liberty Dollars.
Here is some of my feedback from Reddit sales
Here is my eBay profile with 100% Feedback
Here is my BitcoinTalk profile, where I have probably had the most dealings (Click on "Trust" to see Feedback)
(4 3 Available) Crypto Imperator 10,000 Dogecoins, and some background info. below:
Price per Crypto Imperator 10,000 Dogecoin -- $24
First coming out of Spain in 2014, the 10,000 Dogecoin Series were the first coins ever released by Crypto Imperator, now an established and respected manufacturer of physical crypto coins. With a very low mintage of only 500 coins, some excellent minting strikes, and beautifully complex security holograms, these coins were a hit from the start and quickly sold out. The first wallet-type physical Dogecoins ever minted, each coin contains its face value of 10,000 Dogecoins.
The zinc-alloy 10,000 Dogecoin was first released in June 2014 and is 39mm in diameter with a thickness of 3mm. The denomination on the face of the coin is "10,000 DOGE", and each coin was funded with that amount of Dogecoins by the creator. An appealing yet complex tamper-evident security hologram covers the private key to a unique Dogecoin address containing the coin's funds. The coin can be funded with any amount of extra Dogecoin by the buyer if desired, and can be used as a secure cold storage Dogecoin wallet. If you are ever ready to spend the funds contained within the coin, simply peel the hologram off of the coin to reveal the private key, which you can then import into your Dogecoin wallet of choice (however this will probably reduce the value of the coin as a collectible).
The obverse of the coin features a large centered portrait of a shiba inu dog, the dog breed famous for the "Doge" internet memes and the cryptocurrency Dogecoin. Next to the 'Shibe' is the word "Wow" written in the appropriately chosen font of 'Comic Sans'. Above the Doge portrait reads the slogan, "in shibes we trust", and on the bottom of the coin the denomination "10,000 DOGE" is stamped.
On the coin's reverse is the manufacturer's name "CryptoImperator" across the top and its year of minting "2014" along the bottom, the two sets of writing separated by a beautiful floral print that goes up both sides like a vine. In the center of the coin the tamper-evident security hologram is placed, covering up the coin's private key. Crypto Imperator's hologram is one of the best; there are so many different layers in it and each has a different look depending on which angle it is viewed from (which is why I included so many different pictures). Among the different features that can be seen in the hologram are the words "Crypto Imperator Original", a rocket flying to the moon with the words "To The Moon" present, and a Roman-type figure above 2 pillars and the words "Crypto Imperator". In the center of the hologram a small window is cutout, showing the first 8 characters, or 'First Bits', of the coin's Dogecoin address.
SOLD! (1 Available) Shibanu 50,000 Dogecoin (Un-Funded, DIY physical Dogecoin) and some background info. below:
Price for the Shibanu Dogecoin -- $24 SOLD!
The very first coin released in September 2015 by Shibanu (a new physical crypto coin maker), the Shibanu 50,000 Dogecoin coin is a DIY physical Dogecoin. Each purchase includes 1 coin in a protective flip, and 1 tamper-evident security hologram (for placing a private key and assembling the coin if you choose to do so). This coin has a beautiful gold-plated finish that just shines and pictures do not do it justice.
The Shibanu 50,000 DOGE coin was first released in early September 2015 and is 38mm in diameter with a thickness of 2.5mm, composed of Zinc Alloy with a beautiful and lustrous Gold-Plated finish. The recommended denomination on the face of the coin is 50,000 DOGE, but these coins are unfunded as they were originally sold, and any amount of Dogecoin can be loaded onto them if desired. They can be used as a secure cold storage Dogecoin wallet if you choose to print and place a private key and assemble the coin with one of the tamper-evident security holograms. Please note that these coins are sold unfunded, and do not contain or come with any actual digital Dogecoin value. If you are ever ready to spend the funds contained within the coin (if you've assembled & funded it), simply peel the hologram off of the coin to reveal the private key, which you can then import into your Dogecoin wallet of choice. (This concept can be confusing, just ask if you have any questions!)
The obverse of the coin features the word "SHIBANU" stamped across the top, representing its maker, with "50000 DOGE" (representing its suggested denomination, or face value) stamped across the bottom. A large "D" is stamped into the center, with a Shiba Inu dog leaning on the top, which represents the Doge meme. To the left and right of the large "D" are the phrases "Multus Moneta" and "Multus Fortuna", which roughly translate from Latin to English as "Much Money" and "Much Fortune". The large "D" in the center also has an X pattern behind it, and those surfaces are smooth and shiny strikes, while the background has a nice contrasting textured strike.
The reverse features the word "DOGECOIN" stamped across the top in an arched fashion with the year of issue "2015" stamped across the bottom. There is an indented circular area in the center on the reverse, where a private key can be placed and covered with the provided Shibanu tamper-evident security hologram, if you choose to assemble it and/or use it as a cold storage Dogecoin wallet. Shibanu's first holograms are very appealing on the eye with many different elements, layers, and colors, depending on which angle the coin is viewed from. They feature a repeating "SHIBANU" logo in the background with a dog's paw prints and a rocket heading to the moon in the center, which has a letter "D" and the maker's name "Shibanu". There is also a small window cut out in the center of the hologram so that the coin's "First Bits", or first 8 letters of a Dogecoin address, can be viewed to verify funds contained within.
These coins are DIY (Do It Yourself) physical Dogecoins and as such are sold as unfunded kits containing 1 coin and 1 tamper-evident security hologram. The positive aspect of buying a DIY physical Dogecoin is that you don't have to trust anyone with the private keys to your Dogecoin addresses (and Dogecoin funds). With your coin, your wallet's security will be in your own hands if you choose to generate, print, and place a private key within your coin. The tamper-evident security holograms are designed in a way that if somebody gained access to your physical coin and pulled off the hologram to access your private key, it would be obvious it had been compromised due to a visible honeycomb pattern left across the back of your coin. It is your choice if you want to print a private key and assemble your coin, or leave it un-assembled as it is sold. If you need help or have any questions about generating and printing private keys for your coin, just let us know and we will send you some helpful resources and instructions.
Payment Info.- Bitcoin and/or PayPal Friends & Family highly preferred at the moment (Please leave note/comment line blank if paying with PP F&F) but will also accept PP Goods & Services (add 3% to your total). Also, I almost forgot to add- I will also definitely accept Dogecoins as payment for these physical Dogecoins!
Shipping Info.- $2.25 for basic, tracked shipping in the US via First Class Parcel (no matter if you buy 1 or all 5 coins); this will be extremely well-packaged in a bubble mailer and comes with tracking and delivery confirmation for free. If you want Priority 2-Day (which includes $50 insurance), just add $5 to your total.
Always willing to ship international at cost, and can do so very affordably. PM if interested in buying overseas.
Also- I package very securely & discretely, and drop off each package by hand- so once it's shipped you own it unless you want to pay extra for insurance. I will say though I have never had a package lost out of hundreds (knock on wood..)
About Physical Bitcoins/other cryptos:
In 2011 a man named Mike Caldwell, an avid supporter of cryptography and Bitcoin, had an idea to mint physical coins that could represent digital Bitcoin value in a more conventional way, so that more people would be able to conceptualize and understand this new digital cryptocurrency technology. He came up with a way to mint a physical coin that actually contained the digital Bitcoin value it represented. On one side of the coin, he had a recessed groove stamped into it. He then securely and safely generated new Bitcoin address public & private keys, printing the private keys (needed to spend the funds) and placing them in the recessed groove. He then had complex & layered tamper-evident holograms created to cover the private key, which served 2 purposes: 1- these complex holograms made it harder to ever create a believable counterfeit of his coins, and 2- when the holograms were peeled back exposing the private key needed to spend the funds, it left a honeycomb pattern behind, which would instantly tell someone considering buying one on the 2nd market whether the coin still contained its valuable BTC funds, or if it had been spent. He called his coins Casascius physical Bitcoins, and they proved to be very popular, with several different denominations and Series released over a couple years' time. Today these coins are highly valued & sought after collectors' items. Many individuals, groups, and companies followed suit in the years that followed, designing and minting their own physical crypto coins. And that's where we are today with these coins I have for sale. :) I tried my best to explain how physical Bitcoins/Dogecoins/etc. work in a limited space, but it is hard to fully summarize such a topic in so few words, so if you have any questions just ask!
This can all sound so complicated and confusing to someone unfamiliar with Dogecoin/cryptocurrencies and how they work. If you have any questions about these coins or Dogecoin in general, please reach out to me via a message and I would be glad to help you out!
Thanks for Reading!

What is wrong with my current cold storage method?

Today we are going to discuss cold storage and some specific problems with cold storage. While this applies directly to the Secret Key portion of a key-pair; it also applies to the seed used to back up HD wallets and hardware wallets.
The best way to keep you seed/secret key safe is to have multiple copies in multiple locations perhaps with multiple formats and even better if the keys are split. However not everyone has access to multiple locations, or access to land long term, or more than one place to store their things. This is an examination of faults with individual methods; and not a comprehensive plan, obviously.
Not to say everything is all bad but there are many potential weakness out there, and some in the Bitcoin and crypto community like to know the edge cases of things.
I will also highlight some of the aspects of the Keyois Capsule which is a 'physical bitcoin'.
A physical Bitcoin is a cryptographic key pair, a physical key printed and affixed to what has always been before a coin. The first physical bitcoin coin was the Casascius coin, since then the world of physical bitcoin coins has blossomed as a fun part of the Bitcoin world.
We will focus on mediums relating to cold storage and not ones designed for more everyday use, but this applies to the seed you save to keep your everyday spending wallets safe and backed up.
We will assume you generated your keys securely and that you already have them on some medium. We will also have to ignore endpoint physical security because they can all be carried away the same. Remember your cell phone /hardware wallet/ computer client are only as good as where you put the backup seed phrase, which can be thought of as data much like the SK discussed below.
Written on a piece of paper
Printed on a piece of paper
On laminated paper
Engraved / etched/ ablated/ stamped on a piece of metal
Stored digitally on a computer
Stored digitally on CD, floppy disk, laserdisc, or mini-disc
Stored digitally on a flash drive
Backups are essential for digital data Computer code for performing operations can be corrupted in transfer or in operation. Special systems exist and procedures help data to last longer. For ideas, see this archive.gov page Remember to store in multiple locations. You can lose everything in single structure
A physical bitcoin coin
**What can solve most of these problems? A combination of good backup procedures and encryption. **
If you have permeant access to more than one location (people who live in big cities, without family or cars have a hard time with this) or have people you trust with your money (don't) then look into using some form of Multi-signature option.
The Keyois Capsule is a crypto piggy bank; it can be funded from the outside but you to break it open to get them out. You give me a BIP38 encrypted key pair (well the address not the public key) and I engrave it in this tamper evident and time resistant package. You still have to hold on to the pass phrase that allows you to decrypt it; that is however the same problem as all methods with BIP38 encryption. How to store this without having to trust anyone but still being assured of it's security?
  • Engraving, embossing, or stamping on a sheet of metal is one option; however the metals that are easiest to stamp are ones that melt in a house fire. They could be put in a glass jar that's filled with aerogel and buried. These is the best readily available option for most people but it really can be tedious. - This puts you back at anyone who can see it can steal it so dip in plastic dip, wrap in duct tape, bake in clay, encase in concrete, whatever just don't leave unencrypted keys visible!
  • The cryptosteel is another ready-made option
  • Have the words etched onto glass at home with off the shelf products; but be carful of this idea because the glass can shatter from impact and heat or even sudden temperature changes
  • Anodize the words yourself on a pieces of metal, there used to be a service to help use your home printer to print the words with some chemicals you can buy
  • Bake them in clay, then encase that in epoxy resin so it can't shatter. then paint the outside, in the future you can solvent the paint off and see the written seed
  • Use a combination of techniques to split the seed so that it is safe(because split and separated) and redundant (because backed up).
The most cost effective way for a 'normal' person (without their own land, without more than one location, and who cannot trust anyone else with their funds) to keep their backup seed/ secret key safe from damage from the elements would probably to buy a stamping kit and hammer and some stainless steel sheet or bar, Aluminium can be okay if you have the right alloy but better safe than sorry.

Early Timeline of Casascius Physical Bitcoins

Wired recently reported that Mike Caldwell's Casascius Physical Bitcoin service was halted due to being categorized as "money transmission" business by FINCEN.
Curious to learn more about the coins and why they were created, I prepared a short timeline from postings on the Bitcoin Forum.
December 30, 2010
Member tcatm describes a prototype he created for a phycical bitcoin and posts an image:
I just made a "real" bitcoin. They'll eventually be made of real metal instead of glass epoxy + copper once I have better tools.
The post receives positive responses with many suggestions, including one from Caldwell.
January 7, 2011
Caldwell proposes "a tangible bitcoin that actually conveys BTC":
The point would be making BTC conveniently tradeable, like cash. It lowers the minimum required IQ to participate in the Bitcoin economy, which would really help Bitcoin be accepted as mainstream currency.
His first idea was to load bitcoin onto a "pre-denominated smart card". Reaction to the idea is mixed. Member Mike Hearn quickly questions the usefulness of a physical card when the balance could only ever be verified by a computer connected to a network:
... it's very easy for you to pay me with a used up card. I would then pass it on (why redeem it, it's cash!) and it'd pass between people until one day somebody wanted to send the cash electronically. Only then would they discover the card had already been redeemed and was useless.
June 24, 2011
Undeterred by skeptics, Mike continues to iterate on his idea for a physical payment method backed by Bitcoin. This time, he suggests selling paper bitcoin wallets though PayPal. Wallets would be printed using an offline keypair generator.
Although the idea receives some interest, most responses are negative. One member member called the idea "too complicated and messy for the average Joe." Another stated that "No one in their right mind would trust an unknown 3rd party with full access." Another summed the idea up in one sentence:
I can't even begin to understand how you could think that this would be a viable business.
August 15, 2011
Member RSantana announces physical bitcoins he's minted (image) and links to a website selling them.
August 19, 2011
Caldwell announces the coming availability of physical bitcoins for sale (image):
Each coin has a private key embedded inside worth 1 BTC, covered by a custom Casascius hologram. ... Diameter: 1.125 inches. Material: brass. Price subject to revision with Bitcoin price fluctuations. The back side is flat for the hologram, except for a small circular well which holds the private key. The first 8 characters of the public Bitcoin address are visible on the outside, pre-printed on the hologram by the hologram manufacturer.
Reactions range from offers to buy to questions about long-term viability. The same day, member spiccioli points out that the Latin inscription on the front side, "VIRES IN NUMERIS", should have read "vis in numeris".
September 6, 2011
Caldwell announces the availability of Cassascius Physical Bitcoins (image). Reactions are numerous, and mostly positive.

Dogecoin Wallet Import Format

Hi,
I'm trying to use the Bitcoin Address Utility to integrate some address generation in my C# app.
Unfortunately, my ignorance is getting the best of me. The utility generates addresses using a specified type (0 = bitcoin, 30 = dogecoin), and the public address resolves in dogechain eplorers but the Base58 string created from the private address starts with '5' and is 51 bytes, not 'Q' or 52 bytes, so I can't import them into my DOGE wallet.
What am I missing?

Want some personalized vanity addresses for your currency of choice? Check out Vanity Pool

I run a small project called Vanity Pool, it lets you outsource generation of cool vanity addresses through a split-key address algorithm - this means that your private key and thus your money is secure, even though other people mined for your address. This also means that you can get some nice vanity addresses and not have to spend a lot of your GPU time mining for the address instead of mining for your coin of choice.
So if you want some cool vanity address, like DDogeWowAA2EFcGmipzDjQBYQFXiqC8QFs or 1PiachuEVn6sh52Ez7o6Fymvw54qvQ4RBm , head on over to https://vanitypool.appspot.com/ , request a pattern you wish created (shorter patterns area cheaper and take a lot less time to generate), put in a public key that you own (you will need to use it later), when asked for network prefix, put in the decimal version of your coin-specific net-byte. Afterwards, you will be requested to pay a bounty in BTC (creating coin-specific pool would make the mining power a lot smaller; miners prefer being paid in BTC). After the payment is confirmed, any miner connected to the pool will start looking for the solution to your pattern.
Once you have the solution, either use Casascius' Address Utility, or head on over to our online tool (use coin-specific hex NetByte and hex Prefix Byte). After that you can import your new vanity address to your client by going through those steps (example using Dogecoin client).
Have fun!

Bitcoin banknote network? (Blocknotes)

I know that this is sort of a technological step backward but couldn’t we use the split key generation and vanity addresses to make bitcoin banknotes? (see Split Key used by vanity pool and casascius)
I'm no expert but I have been trying to think of a scheme that would work because I don’t like the fact that paper wallets can't be passed around securely.
Here is a vague idea of how it MIGHT work:
Users and miners could create a vanity address (A+B) and fund the address leaving the private key unknown to anyone. If trusted miners kept the address B secret and the banknote contained Address A (along with a lot of other information that proved the amount of BTC) and the user could prove to the mineprintewhatever that they were in possession of the banknote in order to get Address(B) it would ultimately be redeemable because the user could then create the private key for (A+B)
I know there would have to be a lot more to it than this to prevent double spending, counterfeiting, etc. (blockchain?) but I wanted to see if this idea would be practical and get it off my chest. I think it would be cool if users had the option to print, circulate, or redeem banknotes backed by bitcoin.
I suppose once you need to go online to verify the banknote is valid it becomes kind of redundant but the idea is that If people had incentive to print "Blocknotes" eventually we could have a decentralized printing system with different makers of advanced polymer or cotton blocknotes and coins that the people knew and trusted.
