The special United States Bicentennial coins carried the double date 1776–1976.
The United States Mint issued the commemorative circulating quarter, half dollar, and dollar in 1975 and 1976. Instead of showing a single year, each coin bore the paired dates 1776–1976 to connect the coin directly to the nation’s 200th anniversary.
The denominations were the Washington quarter, Kennedy half dollar, and Eisenhower dollar. Congress temporarily authorized redesigned reverses for these three coins, making the Bicentennial issue distinctive in everyday American currency.
A common misunderstanding is that coins dated 1975 were minted for the three denominations. The coins themselves used the double date rather than a separate 1975 date. They were struck in both copper-nickel and silver versions, with collector issues produced at the San Francisco Assay Office.
