The Golden State Mint 1oz Silver Bitcoin Bullion Round is an undated private-mint issue from the Cryptocurrency collection. Struck in one troy ounce of .999 fine silver to mint-fresh quality, it combines Bitcoin imagery with a circuit-style decentralised-consensus design and the Latin inscription VIRES IN NUMERIS, meaning Strength in Numbers. Its confirmed 39.30mm format, reeded edge and tube-or-flip packaging make this a properly identified modern silver round rather than a speculative dated Bitcoin entry.
