First minted in 2000, the Sacagawea Dollar coin honors the legendary Shoshone woman who aided the Lewis & Clark Expedition from 1804 until 1806. Without her navigational and translating skills, the mission would have failed. This unique coin shows a three-quarters profile of Sacagawea with her infant son, born during the journey, on her back. The reverse features a soaring bald eagle, one of the most powerful symbols of our nation.
