The 2018 Sacagawea Native American Dollar is part of the U.S. Mint's continued effort to celebrate the contributions of Native Americans and their cultures. This coin features an image of Sacagawea, a Shoshone woman who played a crucial role in the Lewis and Clark Expedition, on the obverse side. The reverse design often highlights a specific theme related to Native American history or achievements; for 2018, it celebrates the "Big buffalo" Native American code talkers during World War I. Coins minted at the Denver facility are identified by a "D" mintmark. Collectors value these coins for their historical significance, unique designs, and limited availability, particularly in uncirculated or proof conditions.
