Eisenhower Dollars, specifically the 1976 San Francisco issue, are part of a coin series minted in honor of President Dwight D. Eisenhower. These coins were produced to commemorate the United States Bicentennial and feature a dual design, with a depiction of the Liberty Bell on one side and an image of Eisenhower on the other. The 1976 versions were struck in both copper-nickel and 40% silver, with the latter being more sought after by collectors due to its silver content. Collectibility is influenced by factors such as condition, mint mark, and demand among numismatists.
