The Morgan Dollar is a historic silver coin minted by the United States from 1878 to 1904 and then again in 1921. The coin features a portrait of Lady Liberty on the obverse and an eagle on the reverse. The 1881 Morgan Dollar is particularly notable among collectors, as it is known for its high-quality minting and relatively high availability in the market. The coin's value varies based on its condition, mint mark, and rarity, with examples in uncirculated condition commanding higher premiums. It is part of the broader category of U.S. collectible coins, which includes various denominations and historical significance.
