NGC-certified Sacagawea-Presidential Dollar Mule Featured in April Heritage Auctions Sale

The first-known example of a Sacagawea-Presidential Dollar Mule, which was recently certified by Numismatic Guaranty Corporation® (NGC®), is being showcased in a Heritage Auctions sale this spring. Bidding is open now through April 22-26, 2021.

The spectacular modern-day mint error is graded NGC Mint Error AU 58, with the important Discovery Coin attribution included on the NGC certification label. The error occurred in 2014 at the Denver Mint, which struck 5.6 million Sacagawea Dollars and 15 million Presidential Dollars that year.

A mule is created when two dies that were not meant to be paired together are used to strike a coin. In this case, the mule has the obverse of a Sacagawea Dollar, which features the Native American woman’s portrait and the reverse from the Presidential Dollar series that shows the Statue of Liberty.

The Sacagawea Dollar series began in 2000, and the Presidential Dollar series started in 2007. The two coins use the same planchets in the minting process — a copper core surrounded by manganese brass that measures 26.5 millimeters in diameter and weighs 8.1 grams.

The mule was reportedly discovered in a mixed bag of coins obtained from a bank. Other Sacagawea Mules have been reported, including ones involving the Statehood Quarter series. Two of these certified by NGC each realized over $100,000 at Heritage Auctions sales in 2019.
