Morgan dollar [SEP] Introduction
The Morgan dollar was a United States dollar coin minted from 1878 to 1904, and again in 1921. It was the first standard silver dollar minted since the passage of the Coinage Act of 1873, which ended the free coining of silver and the production of the previous design, the Seated Liberty dollar. The coin is named after its designer, United States Mint Assistant Engraver George T. Morgan. The obverse depicts a profile portrait representing Liberty, while the reverse depicts an eagle with wings outstretched. The mint mark, if present, appears on the reverse above the "o" in "Dollar". The dollar was authorized by the Bland–Allison Act.
