The first Silver Dollar in the United States was authorized by Congress in 1792. The first of these dollars, now known as the Flowing Hair Dollar, was issued in 1794 until 1795. Several different issues followed after, including the Draped Bust Dollar, the Liberty Seated Dollar and the Trade Dollar. As far as design went, most of these coins shared the same theme; a depiction of Liberty on the obverse with an bald eagle on the reverse. Of these designs the one that became the most prolific is the Morgan Dollar.
Named for it’s engraver George. T. Morgan, the Morgan Silver Dollar was issued from 1878 until 1904. It weighed 26.73 grams and was composed of .900 silver and .100 copper. Mintage briefly resumed in 1921 before it was replaced by the Peace Dollar. The Peace Dollar had the same specifications as the Morgan and was designed by Anthony de Francisci. The Peace Dollar was minted from 1921 to 1928, and then again briefly in 1934-35. The U.S. Mint did not produce another dollar coin again until 1971, when it issued the Eisenhower Dollar.
Eisenhower Dollars, also referred to as “Ikes” like their namesake, were issued from 1971 until 1978. Only certain issues of the Ike Dollar contained silver, and even then their composition was only 40% silver. These 40% silver coins are available under the “Blue Ike” and “Brown Ike” listings.
