Using the “Redeem Private Key” feature under the Funding Options menu. How Do They Work, and how can I be sure the coin has any value ? : Casascius coins use the “minikey“ private key format. ( ) This “private key” is on a card embedded inside the coin, which is protected by a tamper-evident hologram (the attractive shiny side of the coin). The tamper-evident hologram leaves behind a honeycomb pattern if it is peeled. If the hologram is intact, the bitcoin is ‘good’. An 8-character code is visible on the hologram & this is the first eight characters of the Bitcoin address assigned specifically to the coin. You can verify the coin’s balance by typing this code into the search box (scroll down the page to find it) on There is a mathematical relationship between the Bitcoin address and the private key inside the coin. The digital bitcoin is actually located on the public “block chain” stored on the Internet, but it is completely inaccessible to anyone unless the private key from the coin is loaded into a Bitcoin wallet. For instance one of the coins (I will be listing the other coin’s codes shortly) for sale has the following code visible, 1CcSiC98, go to and type in the code to check the coin’s balance. A note on redeeming the coin at You’ll need to go into your account, go ‘Funding Options’, ‘Add Funds’, ‘Redeem Private Key’. Enter the 30-character code that you revealed underneath the hologram, ignore the 8 characters on the front of the coin. Put any message you like in the description. If the codes are typed correctly (case sensitive, type them as you see them, upper and lower case) you should get a message saying the code’s been accepted. It will not show on your account for 1-2 hours. If you’ve put the code in incorrectly you’ll get a message to that effect. It takes a while to update, it looks like nothing is happening for at least an hour (or more), then as if by magic your account will update with the BTC funded to the coin. Hope this helps.
