Also known as a crypto-currency because of its anonymous nature, Bitcoin is not issued by a bank or backed by any federal reserve around the world. The currency is entirely digital and does not exist in any physical form. These 1 oz Proof Bitcoin Silver Commemorative Rounds are a physical manifestation of the popular crypto-currency, but have no actual value as either a Bitcoin or any other type of currency. On the obverse of the 1 oz Proof Bitcoin Silver Commemorative Round you’ll find the iconic Bitcoin symbol. Engravings include “AOCS Approved, ” “Bitcoin – Digital – Decentralized – Peer to Peer, ” and One Oz. The reverse of each Bitcoin Silver Round includes a similar electronic coding design in the background field, with a matte finish square in the upper-left design field that includes the initials of Michael Bruce and the year of issue. All of the 1 oz Proof Bitcoin Silver Commemorative Rounds have a mirrored finish to the design’s background field, enhancing the visual beauty of each piece. Osborne Mint struck these silver rounds for release. Located in Cincinnati, Ohio, Osborne traces its history back to 1835 and holds the title as America’s oldest private minting facility.
