What Is the 2011 Sacagawea Dollar?
The Sacagawea Dollar, first minted in 2000, honors the Shoshone woman who helped the Lewis and Clark expedition. It shows Sacagawea with her baby on the front and, for 2011, a design of a peace pipe exchange between Native Americans and settlers on the back. About 49.5 million were made in Philadelphia in 2011, so most are worth just $1. But a rare few with errors, like an upside-down back, are worth thousands or millions.
Why Is the 2011 Reverse Error So Valuable?
The 2011 Sacagawea Dollar with a reverse rotation error has the eagle or peace pipe design flipped 180 degrees compared to the front. This mistake, called a “rotation error,” is super rare, with only a handful known to exist. In August 2025, a near-perfect (MS-68) error coin sold for $2.2 million at Heritage Auctions, setting a record for modern U.S. coins. Its scarcity, perfect condition, and dramatic error drive its value.
The $2.2 Million Coin Story
In early 2025, a collector in Pennsylvania found a 2011 Sacagawea Dollar in a bank roll. Noticing the back was upside down when flipped top to bottom, they sent it to PCGS for grading. Confirmed as a rare 180-degree rotation error, it sparked a bidding war at auction, selling for $2.2 million. This find shows that valuable coins can still be hiding in everyday change.
Key 2011 Sacagawea Dollar Errors to Look For
Here are the top errors collectors seek:
1. 180-Degree Reverse Rotation Error

- Value: $100–$1,000.
3. Off-Center Strike
- Why Rare: The design is misaligned, missing parts of the image.
