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.
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 - For 1 BTC I'd be paranoid enough to recommend downloading the source and doing everything offline:
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.

Physical Bitcoin For Sale on eBay for $99,000

A physical bitcoin (BTC) is selling on eBay for $99,000, a listing on July 1 shows.

The seller claims the “collector’s must have” is a Casascius brass token that was created in 2011.

According to the listing, the physical coin is loaded with one BTC that has not been redeemed, and all of the seals remain intact.

Payment can be made in crypto or cash, and the seller says they will also consider trading it for real estate. However, the listing adds that “Cars and boats = no.”

The seller says they made the purchase back in 2012 and have kept it in their safe since then, adding: “Only a few hundred remains in the ENTIRE world.”

They all seem to have signs of wear on the S,I,N,E,R, and I of the ‘Vires In Numeris’ motto, seemingly created in the minting process. Casascius later released an unknown number of 40 coin rolls without holograms as blanks, identifying them as ‘Roll Your Own’. Such a roll came with sheets of laser cut private key tabs and solid gold colored stickers allowing the buyer to create their own coins by using either the provided private keys or by inserting their own. This sale was likely done due to excess stock of Bitnickels.

How to redeem a 2011 Series 1 Casascius BTC?

Hi Bitcoin!
I'm relatively new to crypto and trying to help a family friend cash out their 2011 Series 1 Casascius BTC. They are getting up there in age and want to cash out. I'd buy them out but I simply don't have the funds. I know the coins are relatively collectible, but they're set on cashing out. Can someone walk me through the process of redeeming one of these to the point of transferring to a bank account?
Most of the resources online are pretty dated so I'm curious if there's a way in 2018 that can make this easy?
Forgive me if I follow up with seemingly silly inquiries, I'm really new to this, just trying to do a favor for a friend. Thank you!

WARNING: is a scam

I have been shocked to see this site floating around, and even more shocked to see people using it. claims to use the Casascius Escrow Scheme for trust-free transactions, but this is an obvious LIE.
The site emails codes to each party and requires both codes to redeem funds, but that means the server can spend from the escrow address at any time.
Even more obviously, upon redemption they take a 1% fee and send the rest of the balance to an address you choose. How do you think they can do this, unless they control the private key to the bitcoin escrow address?
Closer inspection of the source also reveals none of the client-side javascript required for this type of system.
This is not trust-free escrow.
The FAQ is a lie.
This site is a scam.
They are likely waiting for someone to try a larger amount before running off with the money.
Hopefully this helps someone and prevents future victims.

How will the "Bitcoin Cash" fork affect Casascius physical Bitcoins?

I'm sure there are many people holding the physical Casascius coins. Can anyone elaborate on how they will be affected during the upcoming "Bitcoin Cash" fork? Will holders of these coins still have BCC as well as BTC, and will they be able to access the funds say, years from now?
Ideally a Casascius holder would never redeem a physical Bitcoin due to its numismatic value; just trying to get some reassurance that holders of these coins would still have access to BCC since technically the private key is with the holder of the coin.

Redeeming a casascius coin

So far every method I've tried has failed. The official website ( lists these options:
For example, you can enter (or "import") your coin's private key code directly into Bitcoin clients such as Armory,, or directly into Mt. Gox as a deposit method.
Well, Armory seems to be busted and is stuck in Offline Mode and their support/twitter is dead. doesn't seem to allow private keys import or at least I've had zero luck finding it. And Mt. Gox, yeah you already know.
Does anyone know how to actually redeem one of these things?

Casascius Physical Bitcoins...

So I have a couple of these casascius physical bitcoins purchased back in 2013 and they remain unredeemed. What are peoples thoughts on their validity in their current state? Leave them as is or should they be moved to my ledger. I've been stung by a shit whom I purchased a 3rd party physical bitcoin (not a casascius) from and he only went a redeemed it himself earlier this year!

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.

Question About Physical Lealana Coin I Bought

I purchased a Lealana 1LTC Litecoin on eBay. I have a few Bitcoins, but don't really know much about Litecoin. (It was an impulsive purchase.)
My questions:
  1. Where do I check to make sure the coin is "loaded"? With physical Casascius bitcoins, I can go to a site and enter the first digits to check a coin's status (loaded/redeemed/not activated). Is there a similar site for Lealana's coins?
  2. I was researching general information on Lealana coins, and I sure couldn't find much. I was hoping to find how many were made, which different types/series were produced, and when she produced them.
  3. Not sure if anyone here updates the Litecoin wiki, but if you do, an article with some basic information on these coins would be appreciated.
Thanks in advance for any help. Looking forward to learning more about litecoins.
I emailed Smoothie. His response was as follows:
I've made approximately 4,000 of the 1 LTC brass coins (in circulation).
They were made in 2013. I've stopped selling coins for now.
I've created 1 oz 25 LTC, 1/2 oz 10 LTC, and 1/4 oz 5 LTC coins. All made in 2013. Quantities are 500, 1000, and 2000.
You can type in the first bits into to check balance.
Hope this helps.
Aloha Smoothie
Thanks for your help everyone!

Physical Bitcoin and OpenDime users face dilemma -- reveal key to dump BCash, or hodl both

You might not open up a Casascius just to get at the little bit of BCash inside, but a replacement OpenDime is just $15. Meaning if you held more than maybe $200 worth of bitcoin on your OpenDime it starts making economic sense to order a replacement OpenDime and just cash out the BCash ($BCH) on the old one.
Paper wallets don't require any seal to be broken to spend the BCash, however to not weaken the wallet's security you would not want to dump the $BCH yet hodl the $BTC yet (due to that spend transaction revealing the public key.)
Trezor has it all figured out for you.
What would be useful is what Satoshium would offer. It has the transferability of cash (in the same manner that OpenDime, for example, does), and the re-usability of a Trezor (as a funded Satoshium can be redeemed, then reset back to blank state for use in funding with a new address.) . Unfortunately, Satoshium is still at just the concept (white paper) stage.

Offline IRL transactions

Longtime Bitcoin advocate here. Just recently purchased a Bit-card for the novelty, and I can't help but wish for a physical, antiquated method of transacting bitcoins physically off of the blockchain that sincerely hinders or eliminates double-spending or counterfeiting while never or rarely needing internet access.
I'm from New Orleans, and picture bitcoins being impossible to use in the aftermath of a hurricane. If you live in the Northeast US, snowstorms can cause power outages for days. During these times, though not daily, people can still transact with cold hard cash. I personally don't think Bitcoin will replace fiat money entirely, but I do wish there was a way to trade it physically for rough times.
Casascius coins, bit-cards, and other products protect private keys with holograms, tamper proof stickers, etc. They usually contain public addresses and verification addresses to make sure the card/coins are loaded and aren't fake. But any skilled counterfeiter could easily hand their coin in and it have a valid verification link and public address with absolutely no private key underneath the sticker. Likewise, skilled con-artists could replace the holograms or stickers and "spend" the coins, immediately sending the digital coins afterwards before they can be redeemed.
While it wouldn't be trustless, I was wondering if anyone had any ideas on how to make paper wallets, coins, cards, or whatever that make counterfeiting extremely hard and/or impossible? Right now, commercial paper-wallets for trade without internet aren't worth it, considering the risks and costs.

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.
