Sacagawea Dollars are a series of golden-colored one-dollar coins issued by the United States Mint, first released in 2000. They feature a depiction of Sacagawea, a Shoshone woman who helped the Lewis and Clark expedition, on the obverse and a soaring eagle on the reverse, designed by artist Glenna Goodacre. The coins were produced primarily for circulation but have also become popular among collectors, particularly for certain years, such as those struck in 2021, which may have different mint marks or finishes that add to their numismatic value. The coins are often sought after for their historical significance and unique design.
