The U.S. coins issued for the 1976 Bicentennial carry the double date 1776–1976.
The special circulating set included a Washington quarter, Kennedy half dollar, and Eisenhower dollar. Their reverses received temporary designs connected with the Bicentennial, while the obverses carried the shared double date.
The coins were struck during 1975 and 1976, but the date shown commemorated the 200-year span from 1776 to 1976. This distinction explains why some Bicentennial coins were minted before the anniversary year while still bearing the same commemorative date.
The issue was not limited to a single denomination. The quarter, half dollar, and dollar all participated in the program, making the double date one of the most recognizable features of American commemorative coinage from the period.
