Eisenhower Dollar coins, also known as Ike Dollars, were issued by the United States Mint from 1971 to 1978. The coin features President Dwight D. Eisenhower on the obverse and an image of the Apollo 11 moon landing on the reverse. The 1971 Denver Mint version of the coin was struck in a copper-nickel alloy and has a distinct size and weight, making it a popular collectible among numismatists. These coins are notable for their historical significance and varying mintmarks, with the Denver Mint's "D" mintmark identifiable on the 1971 issues.
