Minted to encourage trade with the Far East, U.S. Gov’t Trade Dollars are the only U.S. coin to have their legal tender status revoked. Minting officially ended in 1883, but rare examples of 1884 and 1885 dates have surfaced, thought to have been created by unscrupulous Mint employees. This privately minted non-monetary tribute proof salutes the final 1885 date and is clad in 71mg .999 Pure Silver.
