Eisenhower Ike Dollars were issued by the United States from 1971 to 1978, featuring President Dwight D. Eisenhower on the obverse and an image of the moon landing on the reverse. The coins were minted in both silver and base metal versions, with the silver variety being composed of 40% silver. The 1978 Eisenhower Dollar is notable as one of the last years of minting for this series. Collectors often seek these coins for their numismatic value and historical significance.
