The Story of the 2011 Sacagawea Dollar
The Sacagawea Dollar is a unique coin that honors a key figure in American history. Its rare errors have turned it into a collector’s dream.
Honoring a Native American Hero
First minted in 2000, the Sacagawea Dollar celebrates Sacagawea, a Shoshone woman who helped guide the Lewis and Clark expedition. The front (obverse – main side) shows Sacagawea with her baby, Jean Baptiste, while the back (reverse – other side) changes yearly to highlight Native American history. In 2011, the reverse featured a peace pipe, symbolizing treaties with Native nations. About 49.5 million were minted in Philadelphia (no mint mark) and Denver (“D”).
The $2.2 Million Error
In 2011, a tiny batch of these coins had a rare mistake: the eagle or peace pipe on the back was rotated 180 degrees, appearing upside down when flipped top to bottom. This error made one coin sell for $2.2 million at a Heritage Auctions sale in August 2025.
Why the 2011 Sacagawea Dollar Is Worth $2.2 Million
Several factors make this coin a collector’s jackpot:
Rare Rotation Error
The 180-degree reverse rotation error is extremely uncommon due to modern minting technology, which rarely allows such mistakes. Fewer than a dozen of these error coins are known to exist.
Near-Perfect Condition
The $2.2 million coin was graded MS-68 (near flawless) by a professional grading service, with sharp details and no wear, boosting its value.
Historical Significance
The Sacagawea Dollar celebrates Native American contributions, and the 2011 design honors diplomacy, adding cultural value that excites collectors.
High Collector Demand
With more people collecting modern error coins, bidding wars at auctions like Heritage pushed the price to record levels for a modern U.S. coin.
How to Spot a 2011 Sacagawea Dollar With a Reverse Rotation Error
Think you’ve found a treasure? Here’s how to check:
Check the Year and Mint Mark
Look for a 2011 date and no mint mark (Philadelphia) or a “D” (Denver) near Sacagawea’s portrait. The coin is golden-colored with a smooth edge.
Inspect the Rotation
Flip the coin top to bottom. If the eagle or peace pipe on the back is upside down compared to Sacagawea’s face, you might have the error. Use a magnifying glass for clarity.
Test Condition
The coin should look shiny with no scratches or wear. Don’t clean it—cleaning can ruin its value.
Verify Authenticity
Fakes exist, so take it to a professional grading service like PCGS or NGC to confirm the error and value.
Are These Coins Still in Circulation?
Yes, it’s possible! Since 49.5 million 2011 Sacagawea Dollars were made for circulation, some with the rotation error could still be in change, bank rolls, or vending machines. Check your dollar coins carefully
