2000 Sacagawea dollar – Washington quarter mule


The 2000 Sacagawea dollar – Washington quarter mule is an error coin featuring the obverse of a Washington 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.

History

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