This is the first bitcoin themed coin to be produced and sold. Released on June 28th, 2011, these were sold out over a month before the first Casascius coins went on sale. Being sold for 1.50 GBP each with a minimum order of 10, supply ran out in two months. Due to the initial cheapness of these coins, it is likely that many were damaged by mishandling and/or misplaced over the years. As such, the number of these coins in good condition is likely very small, and one coming onto the market is a rare event.
