Imagine pulling a dollar coin from your wallet and discovering it’s worth over two million dollars. That dream became reality when the rare 2011 Sacagawea Dollar with a reverse rotation error sold for $2.2 million at a 2025 auction. This mistake, where the back of the coin is flipped upside down compared to the front, turned an ordinary dollar coin into a collector’s treasure. Let’s explore the story of this remarkable coin, why it’s so valuable, and how you can check your own coins for this error.
The Story Behind the Sacagawea Dollar
The Sacagawea Dollar was first introduced in 2000 to honor Sacagawea, the Shoshone woman who played a crucial role in guiding Lewis and Clark during their famous expedition. Its golden appearance comes from a manganese brass coating layered over a copper core.
The 2011 edition carried the theme of Native American treaties. The obverse, designed by Glenna Goodacre, depicts Sacagawea carrying her child. The reverse for that year shows hands exchanging a peace pipe, symbolizing the historic Wampanoag Treaty of 1621. Around 49.5 million coins were minted in Philadelphia and Denver, making most of them worth only face value—unless they contain a rare error.
What Is a Reverse Rotation Error?
A reverse rotation error occurs when the back of a coin is misaligned with the front. Normally, when you flip a coin top to bottom, both sides face the same direction. On the 2011 Sacagawea Dollar with this mistake, the reverse design appears upside down when compared to the portrait of Sacagawea.
Only a few of these coins have ever been confirmed, which makes them extremely valuable in the eyes of collectors.
Why the 2011 Sacagawea Dollar Is Worth Millions
Several factors combined to push the value of this error coin into the millions.
Extreme rarity
So far, only a handful of 2011 Sacagawea Dollars with this error have been discovered, making them incredibly scarce.
Perfect condition
The $2.2 million coin was graded MS-68 by PCGS, meaning it was virtually flawless and looked exactly as it did when it left the mint.
Collector demand
Rare coins attract fierce bidding wars. Wealthy collectors seeking unique pieces are willing to pay extraordinary amounts, especially when a coin has both historical and cultural significance.
How to Check for the Reverse Rotation Error
If you own a 2011 Sacagawea Dollar, here’s how you can test it:
- Hold the coin with Sacagawea’s portrait upright.
- Flip it from top to bottom.
- If the reverse design of the peace pipe is upside down, you may have a reverse rotation error.
- Look for the mint mark under the date. Many known errors came from the Philadelphia Mint with no mark.
- Inspect the coin’s condition carefully. Do not attempt to clean it, as that will lower its value.
The best way to verify is to take the coin to a professional grading service such as PCGS or NGC.
Could These Coins Still Be in Circulation?
With nearly 50 million coins struck in 2011, Sacagawea Dollars are still found in bank rolls, change, and old collections. The odds of finding one with a reverse rotation error are slim, but it is not impossible. Many rare coins have been discovered years later in jars, wallets, or inherited collections.

The 2011 error coin isn’t the only valuable Sacagawea Dollar. A few others to look for include:

How to Protect Valuable Coins
If you discover a rare coin, proper care is essential to preserve its value.
- Do not clean the coin, as cleaning causes scratches.
- Handle only by the edges to avoid leaving fingerprints.
- Use gloves and store coins in protective holders.
