The double date 1776–1976 appears on United States Bicentennial coins struck in 1975 and 1976.
The United States Mint issued special circulating versions of the Washington quarter, Kennedy half dollar, and Eisenhower dollar for the Bicentennial. Each carried the dual date instead of a single year on the normal obverse design.
The coins were produced in both 1975 and 1976, but none bears the date 1975. Their reverse designs were temporarily changed to commemorate the 200th anniversary of American independence, while the obverse portraits remained associated with Washington, Kennedy, and Eisenhower.
The coin program provided a lasting, everyday reminder of the Bicentennial. It also created a collecting category that connects the 1976 anniversary with the 2026 America250 observance.
