Numismatic Guaranty Corporation (NGC) has released the following Press Release announcing the grading of the first known Sacagawea-Presidential Dollar Mule coin. The 2014 Sacagawea coin has the Reverse of the Presidential Dollar series instead of the Native Hospitality Reverse of that year. This is the first mule of this type to be discovered.
Numismatic Guaranty Corporation® (NGC®) has certified the first known mule of a Sacagawea Dollar and a Presidential Dollar. This incredible error, which paired a Sacagawea Dollar obverse with a Presidential Dollar reverse, was struck in 2014 at the Denver Mint. It is now graded NGC Mint Error AU 58 with a notation of Discovery Coin to recognize its important place in numismatic history.
The Sacagawea Dollar series began in 2000 and is named after the Native American woman who appears on its obverse. The Presidential Dollar series began in 2007, using the same planchets as the Sacagawea series: 26.5 millimeters in diameter, 8.1 grams in weight and consisting of a copper core surrounded by manganese brass.
The edge of this mule sheds some light on its history: It bears the year 2014 and the “D” mintmark of Denver. That year, the Denver Mint struck 5.6 million Sacagawea Dollars and over 15 million Presidential Dollars, almost equally distributed between Warren Harding, Calvin Coolidge, Herbert Hoover and Franklin Roosevelt.
Any 2014 Sacagawea obverse should have been paired with that year’s Native Hospitality reverse, which depicts a pair of Native Americans offering food and a peace pipe. Instead, this mule features the Statue of Liberty reverse from the Presidential Dollar series.
While this is the first Sacagawea Dollar and Presidential Dollar mule known, other Sacagawea Dollar mules have been reported. Two decades ago, NGC was the first third-party grading service to authenticate and grade a Sacagawea Dollar mule that combined the George Washington design from the Statehood Quarter series obverse with the soaring eagle from the Sacagawea Dollar reverse. Several examples of these mules have come to auction in recent years, including two graded NGC Mint Error MS 67 that each realized over $100,000 at sales held by Heritage Auctions in 2019.
The person who submitted this Sacagawea-Presidential Dollar mule to NGC reported making the discovery in a mixed bag of dollar coins obtained from a bank in 2019. It was eventually submitted to NGC for certification.
The industry-leading authentication and grading team at NGC includes David J. Camire, an authority on mint errors who is the co-author of 100 Greatest US Error Coins. In addition to being an NGC Grading Finalizer, Camire serves as President of Numismatic Conservation Services™ (NCS®), an affiliate of NGC.
“This is yet another great find by a collector and an important reminder for the coin collecting community that astonishing discoveries are still being made,” Camire said. “Today, the US Mint uses technology and procedures that make it highly unlikely for mint errors not only to be produced, but also to escape into circulation. When they do, they become highly collectible and the NGC grading team has the expertise and resources to authenticate rare mint errors like these. Now, the hunt is on to see whether additional specimens can be found. Happy hunting!”
