Commemorative Coin Oneida - (ASSOCIATED PRESS)

The reverse side of the U.S. Mint’s 2026 Sacagawea $1 coin will feature Polly Cooper, a woman from the Oneida tribe known for helping George Washington’s Continental Army during the Revolutionary War.

The release of the coin this week coincides with celebrations of the 250th anniversary of the signing of the Declaration of Independence. It recognizes Cooper's role in a 1778 relief expedition from Oneida territory in what is now central New York to the rebel troops' winter encampment in Valley Forge, Pennsylvania, where they were facing a food and supply crisis.
