U.S. Bicentennial quarter, half-dollar, and dollar coins carry the double date 1776–1976.
The United States Mint issued these circulating commemorative designs for the Bicentennial, which culminated on July 4, 1976. The paired dates represented the adoption of the Declaration of Independence in 1776 and the 200th-anniversary celebration in 1976.
The coins were struck during both 1975 and 1976, but all three denominations used the double date 1776–1976 rather than separate annual dates. The special reverses included a colonial drummer on the quarter, Independence Hall on the half-dollar, and the Liberty Bell superimposed on the Moon on the dollar.
These were circulating commemoratives, so people could encounter them in ordinary transactions. Their designs remain among the most recognizable physical reminders of the Bicentennial and provide a direct connection between the 1776 founding era and the 1976 national celebration.
