Rare Sacagawea Dollar 'Mule' Coming to Long Beach


In a press release distributed by Paper Money Guaranty, we have learned that a famous "mule" is coming to Long Beach as one of the consigned pieces.

For those who do not know what a "mule" is in terms of numismatics, it is "when a coin or medal is minted with an obverse and reverse design not normally seen on the same piece."

The "mule" coming to Long Becah is the Sacagawea dollar mule which bears the obverse of a Washington quarter and the reverse of the Sacagawea dollar. According to PMG, "it was struck on the manganese-based alloy planchet used for the Sacagawea dollar.

This so-called "mule" of the 2000 Sacagawea dollar and Washington quarter is graded NGC Mint Error MS 67 and is only one of 18 examples known.

Back in April 2018, we saw the 17th known example of the error achieve a record price of $192,000 during the March Whitman Coin Expo that was put on the block by Stack's Bowers Galleries.
