I was given an actual casascius bitcoin minted in 2011 as a tip, and I'd like to know where I can exchange it for US dollars.

How would I extract the private key from this coin to gain access to the digital bitcoins if I were to sell them online?

You have two routes here:

Sell the physical Bitcoin

Don't remove the sticker on the back. Use a website like localbitcoins to sell it to someone near you.

Some people might want a physical Bitcoin, especially since they're not being made anymore.

Sell the Bitcoin 'contained' within the physical coin.

Peel off the sticker on the back. Inside will be a code that lets you spend the Bitcoin. (I recommend using Blockchain.info as your e-wallet.) You can sell the Bitcoin online or locally.

The remaining brass part is mostly worthless.

  • I was looking for more of a "physical walk in place" to take it to rather than all the online jargon wallet things. My bank should be able to cash this for me, right?

  • @user21748 let us know how that works out but I can't see it happening. I'd sell the coin whole on eBay. Anyone not into Bitcoin either won't care, or won't pay market rate Jan 5, 2015 at 5:10
