Hidden Fortune in Your Pocket Sacagawea Dollar Errors: The Sacagawea dollar, first released in 2000, was intended to celebrate Native American heritage and provide a modern replacement for the Susan B Anthony dollar. While the coin itself has not seen widespread circulation, certain minting errors have transformed ordinary examples into treasures worth astonishing sums. In 2026, collectors continue to chase these elusive rarities, with some error coins fetching prices as high as 2.1 million dollars at auction. This article explores the history, types of errors, collector demand, and auction records that make the Sacagawea dollar one of the most fascinating modern coins in American numismatics.
The Origins of the Sacagawea Dollar
The coin was designed to honor Sacagawea, the Shoshone woman who guided Lewis and Clark during their expedition. Sculptor Glenna Goodacre created the obverse design, featuring Sacagawea carrying her infant son, Jean Baptiste. The reverse depicted a soaring eagle, symbolizing freedom and strength. The coin was struck in a golden-colored manganese brass alloy, giving it a distinctive appearance compared to other U.S. coinage.
Why Minting Errors Occur
Minting errors happen when mistakes occur during the production process. These can involve misaligned dies, missing elements, incorrect planchets, or double strikes. While most coins are carefully inspected, occasional errors slip through, especially in large production runs. For collectors, these errors are not flaws but treasures, representing anomalies that make the coin unique.
Types of Sacagawea Dollar Errors
Several notable errors have been documented in the Sacagawea dollar series. Some are relatively minor, while others are spectacular and extremely rare.
Major Error Types
- Missing Edge Lettering: Some coins were struck without the edge inscriptions that were introduced in later years.
- Double Strikes: Coins struck twice by the press, creating overlapping images.
- Off Center Strikes: Coins struck with the design shifted away from the center.
- Wrong Planchet Errors: Coins struck on planchets intended for other denominations.
- Mule Errors: The most famous type, involving mismatched obverse and reverse dies.
The Legendary Mule Error
The most famous Sacagawea dollar error is the mule coin. In 2000, a small number of coins were mistakenly struck with the obverse of a Washington quarter paired with the reverse of the Sacagawea dollar. This extraordinary mistake created a coin unlike any other in U.S. history. Only a handful of examples are known, and they have become legendary among collectors.
Collector Value in 2026
The value of Sacagawea dollar errors depends on rarity, condition, and demand. While minor errors may fetch hundreds or thousands of dollars, the mule errors are in a league of their own. In 2026, auction records show these coins selling for up to 2.1 million dollars, making them some of the most valuable modern coins ever produced.

Collectors speculate that additional examples may still exist in private hands, waiting to be uncovered. If new coins surface, they will undoubtedly attract enormous attention and potentially set new records.
