I love collecting coins. I asked my sister to give me a sacagawea dollar, one of the two current United States dollar coins and she said she'd give me one. This coin began being minted in 2000 to replace the Susan B. Anthony dollar coins. Sacagawea dollars have a smooth outside edge and distinctive gold color. The coin portrays Sacagawea, a woman who was a member of the Lewis and Clark Expedition. It is the only gold colored coin in the United States that was circulating during those times.
