Created in 2012, this was the first silver coin made by Casascius and a precursor to the 2013 series 3 line of silver coins. Four coins were funded in 2015.
This design builds upon the back of the Casascius 25 BTC coins, resulting in a smooth design that looks good in silver. Very similar designs are found in the coins of Lealana and Cryptolator. The 0’s and 1’s spell out ‘Bitcoin: an idea too big to fail’ in binary.
The same size and weight as the later 1 BTC silver coin,it is significant to note the missing ‘laser rimming’which is present in the 1 BTC silver coins as well as the Lealana 1 BTC Silver Bitcoin line. This coin came shipped within a plastic capsule, protecting it (especially the later ‘Gold B’ design with its less than superior plating) from wear.
*Mintage figures represent both series 2 and series 2 ‘Gold B’ versions; specific numbers are unknown, but the ‘Gold B’ is ssumed to be more rare. It can be speculated that a total of 500 were minted, with seven
rejected and/or retained by Casascius.
