  Casascius Bitcoins are physical coins that contain a private key embedded inside them. They were created by Mike Caldwell and were one of the earliest attempts to merge physical and digital currencies. Each coin has a unique Bitcoin address and a hologram on the back to ensure authenticity. To access the funds, you need to peel off the hologram and reveal the private key. Once you have the private key, you can import it into a Bitcoin wallet and access the associated funds. It's a unique way to store and transfer Bitcoins.
