If your answer is President Dwight D. Eisenhower, you are wrong. If your answer is the First Landing of Man on the Moon, you are wrong. The Eisenhower Dollars were struck to honor President Eisenhower and the First Landing of Man on the Moon. It wasn't until 1975 that the Eisenhower Dollar became a commemorative coin. As you know 1976 was the Bicentennial Year or 200th Anniversary of the USA's independence. The occasion was commemorated on the 1976 Washington Quarter, Kennedy Half Dollar and the Eusaenhower Dollar. All three coins bear the dates 1776-1976. Though Eisenhower Dollars were minted in 1975, none were dated 1975. You realize the San Francisco Mint only struck proof Eisenhower Dollars composed of clad silver during 1971 and 1972. The Mint struck both clad copper and clad silver proof Eisenhower Dollars during 1973 and 1974. For the Bicentennial commemorative issue San Francisco produced both proof and circulation Eisenhower Dollars. The earlier strikes (part of 1975) bore a low relief design and bold lettering desiginated as Variety 1 on their reverses. The later strikes (latter part of 1975 and all of 1976) have a sharp design and narrower, more delicate, lettering (as do all subsequent Eisenhower Dollars). According to the Red Book, The San Francisco Bicentennial Eisenhower Dollars were produced thusly: "1776-1976 S clad copper proofs - variety 1 (2,845,450) 1776-1976 S clad copper proofs - variety 2 (4,149,730) 1776-1976 S clad silver circulation - variety 1 (11,000,000 approx.) 1776-1976 S clad silver proofs - variety 1 (4,000,000 approx.)" Thanks to Wikipedia, you can actually see examples of the 1776-1976 S Bicentennial reverse varieties 1 and 2.
