Eisenhower Silver Dollars were minted from 1971 to 1978. The Eisenhower Eagle Reverse design were minted from 1971 to 1974 and honors both President Dwight D. Eisenhower and the first landing of man on the moon. This design is the work of Chief Engraver Frank Gasparro, whose initials are on the truncation and below the eagle. The reverse is an adaptation of the official Apollo 11 insignia. Collectors' coins were struck in 40% silver composition, and the circulation issue in copper-nickel.
