The Eisenhower dollar is a $1 coin issued by the United States government from 1971–1978 (not to be confused with the Eisenhower commemorative dollar of 1990, or the Presidential $1 Coin Program, which will feature Eisenhower in 2015). The Eisenhower dollar followed the Peace dollar after a lapse of 36 years in dollar coinage and is named for General of the Army and President Dwight David "Ike" Eisenhower, who appears on the obverse. Both the obverse and the reverse of the coin were designed by Frank Gasparro.
The Eisenhower dollar was the last dollar coin to contain a proportional amount of base metal to lower denominations; it has the same amount of copper-nickel as two Kennedy half dollars, four Washington quarters or ten Roosevelt dimes. Because of this it was a heavy and somewhat inconvenient coin. It was often saved as a memento of Eisenhower and never saw much circulation outside of casinos. This led to its short time in circulation and its replacement by the smaller, but even less popular, Susan B. Anthony dollar in 1979.
