This is the first physical crypto-currency in a silver
bar form and second implementation of a ‘bar’ after
Casascius’ various brass bars. ‘Cryptogenic Bullion’
obviously draws parallels to precious metal bullion, making a silver bar (which arguably
conveys the idea of ‘bullion’ better than a silver coin or round), a natural choice to store the
crypto-currency. In mid-2013, Cryptogenic Bullion was re-branded to Crypto Bullion. In
2013, the BTC value of the 10 CBX face value varied between 0.008 BTC and 0.04 BTC.
