Casascius coin – CLC Definition

Casascius – The First Physical Bitcoin
A year after Bitcoin launched, Utah-based Mike Caldwell began minting the Casascius coin, which served as a cold crypto wallet for bitcoins. It was a brass coin into which the private key of the bitcoin was stored. Bitcoin bars were also minted. At the time, bitcoins were worth about $30, and various BTC amounts were purchased with their keys stored in each coin. Within a couple years, the U.S. government shut Caldwell down because it is illegal to mint currency. The C-a-s-a-s in Casascius means “call a spade a spade.” See
