The Sacagawea Dollar is a coin that was first introduced by the United States Mint in 2000, featuring an image of the Native American woman Sacagawea on the obverse and an eagle in flight on the reverse. The 2011 Sacagawea Dollar, minted in Philadelphia, is part of the broader series that aimed to enhance the representation of women in U.S. currency. These coins are primarily made of a copper-nickel alloy and have become popular among collectors due to their historical significance and unique design. Collectors often seek specific years and mint marks, like the Philadelphia mint mark, to complete their sets or for investment purposes.
