From 1971 to 1978, the U.S. Mint issued dollar coins with the obverse depicting Dwight D. Eisenhower and the reverse the insignia of the Apollo 11 moon landing, both designed by Chief Engraver Frank Gasparro. The Eisenhower dollars minted for general circulation contained no silver or gold, but were instead composed of the same copper-nickel clad composition used for the dime, quarter, and half dollar. This made the circulation coins extremely resistant to wear and, like the smaller denominations, they still retain a good deal of shine even when subject to mass usage.
