1971 San Francisco (S) Eisenhower (Ike) Silver-Clad Dollar PF in Original Government Packaging (OGP) (40% Silver)

Honoring 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 of the president's neck, 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.

1971 S Proof Ike Dollar

After 1971, the dies for the Eisenhower dollar were modified several time by changing the relief, strengthening the design, and making Earth above the eagle more clearly defined. Low-relief dies, with flattened Earth and three islands off Florida, were used for all copper-nickel issues of 1971, Uncirculated silver coins of 1971, and most copper-nickel coins of 1972. High-relief dies, with round Earth and weak or indistinct islands, were used for most Proofs of 1971, all silver issues of 1972, and the reverse of some scarce Philadelphia copper-nickel coins of 1972.
