Eisenhower dollars, also known as Ike dollars, were issued by the United States from 1971 to 1978. The 1976 Eisenhower dollar was minted to commemorate the American Revolution Bicentennial, featuring a dual date of 1776-1976. Coins from the Denver Mint are designated with a "D" mintmark. These coins are notable not only for their historical significance but also for their larger size compared to other dollar coins produced by the U.S. Mint. Collectors often seek out the 1976 version due to its unique design and limited mintage.
