The Sacagawea Dollar, also known as the Golden Dollar, was introduced by the United States Mint in 2000 to honor the Native American woman Sacagawea, who played a crucial role in the Lewis and Clark expedition. The coin features an image of Sacagawea with her infant son on the obverse and an eagle in flight on the reverse. The 2022 edition continues this tradition, retaining the coin's original design. Sacagawea Dollars are made of a manganese-brass alloy, giving them a distinctive golden hue, and are sought after by collectors, especially in uncirculated condition.
