A Tiny Error Turns Sacagawea Dollar into a $2.1 Million Treasure
A small mistake on a Sacagawea dollar coin has transformed it into a prized collectible now worth an astonishing $2.1 million. Originally introduced in 2000, the Sacagawea dollar honors the Native American woman who guided the Lewis and Clark expedition. However, a rare variant containing an error has stirred up excitement among numismatists.
This unique coin, struck at the Philadelphia Mint, includes a production blunder that has made it one of the most sought-after modern coins. Let’s uncover what makes this particular coin so extraordinary and how it ended up as a multimillion-dollar jackpot for a lucky collector.
What Makes This Coin So Rare?
This rare Sacagawea dollar is known as a “mule” coin, which occurs when two mismatched dies are used to mint a coin. In this case, the obverse features Sacagawea, while the reverse bears the design meant for a Washington quarter with an eagle.
The error took place at the Philadelphia Mint in 2000 before being quickly detected, meaning very few were produced. Experts believe that fewer than 20 of these error coins exist today. Because of this extreme rarity and the remarkable error, the coin has become one of the most valuable discoveries in modern numismatic history.

| Year Minted | 2000 |
| Mint Location | Philadelphia |
| Error Type | Mule (Sacagawea obverse, quarter reverse) |
| Estimated Quantity | Less than 20 |
| Current Value | $2.1 Million |
How Was It Discovered?
The journey to discovering this rare coin is just as thrilling as its value. In 2000, a few of these unique error coins found their way into general circulation. One alert collector noticed the unusual reverse design while examining a roll of Sacagawea dollars acquired from a local bank.
What appeared at first to be a normal coin turned out to be a striking anomaly. Once authenticated by coin experts, the coin’s value soared. As time passed and the number of known mules remained low, the price continued to climb. A private sale in October 2025 pushed the coin’s value to a record $2.1 million.
Why Collectors Are Going Crazy
Coin collecting continues to be a beloved pastime across the United States, and rare mint errors like the Sacagawea mule are the ultimate prize. This coin’s appeal comes from its blend of historical significance, rarity, and an unusual minting mistake.
It tells a compelling story—honoring Sacagawea, showcasing a major U.S. Mint error, and existing in incredibly limited numbers. Modern error coins are seeing increased demand as more enthusiasts enter the hobby. According to one numismatic expert, “This is the type of discovery people dream of—it’s the lottery ticket of the coin world.”
What’s Next for the Coin?
The buyer behind the $2.1 million purchase has remained anonymous, but speculation suggests it may end up in a private collection or museum exhibit. Some enthusiasts fear it could vanish from public access, while others are hopeful it will appear at future coin expos.
In the meantime, coin lovers across the country are inspecting their change for similar errors. Although the U.S. Mint has significantly improved quality checks since 2000, this sale has reignited public interest. Treasure hunters are now on alert, hoping they might stumble upon another overlooked gem in everyday circulation.
