Silver coins have been a part of US currency since the early days of the nation. The first silver coins were minted in 1794 and were known as Flowing Hair Dollars. These coins were made of silver and copper and were the first coins to be minted by the US government. In 1837, the US government began minting the Seated Liberty Dollar. This coin was made of silver and was the first coin to feature the iconic Lady Liberty seated on a rock. The Seated Liberty Dollar was minted until 1891 and was replaced by the Morgan Dollar. The Morgan Dollar was minted from 1878 to 1904 and was made of silver and copper. This coin featured a portrait of Lady Liberty on the obverse and an eagle on the reverse. The Morgan Dollar was the last silver dollar to be minted by the US government until the Peace Dollar was introduced in 1921. The Peace Dollar was minted from 1921 to 1935 and was made of silver and copper. This coin featured a portrait of Lady Liberty on the obverse and an eagle on the reverse. The Peace Dollar was the last silver dollar to be minted by the US government until the Eisenhower Dollar was introduced in 1971. The Eisenhower Dollar was minted from 1971 to 1978 and was made of silver and copper. This coin featured a portrait of President Dwight Eisenhower on the obverse and an eagle on the reverse.
