The 2000 Sacagawea dollar – Washington quarter mule is an error coin featuring the obverse of a Washington quarter (specifically a 50 State quarter) and the reverse of a Sacagawea dollar struck on a gold-colored dollar coin planchet. It is one of the first known authentic mule coins to be released into circulation by the United States Mint. [2]

History

Mule coins were deliberately produced by US Mint employees for sale to coin collectors in the mid-1800s. [3] However, no authentic (accidental) mules of United States currency were known to exist. This changed in the 1990s, when a Lincoln cent (dated 1993-D) with the reverse of a Roosevelt dime were discovered. [note 1] [5] In 2000, Frank Wallis of Arkansas discovered a Sacagawea dollar with the obverse of a Washington quarter. [6]

List of known coins

As of September 2019, 19 examples have been confirmed, 16 of which are owned by a coin collector named Tommy Bolack. [7] [8] Three different die pairs have been identified among the examples. [7]
