Aztec Calendar Copper Bullion Coin Ring

The Aztec Calendar is minted by the Golden State Mint in America, in both fine silver and fine copper. The level of detail on this 1oz bullion coin is exquisite, it makes for a beautiful ring. This particular ring was made for a client, again engraved by the talented John Dearden. It is of particular interest because it was made to a UK size O (US size 7), which is incredibly small for a 1oz bullion round. This sizing wouldn’t have been possible without expert tooling from Neil Pipet.
