The United States Bicentennial coinage included three denominations: the quarter, half dollar, and dollar.
Congress authorized special circulating commemorative coins for the 1976 anniversary, and the United States Mint temporarily redesigned the reverses of those three denominations. The obverses retained the usual portraits of George Washington, John F. Kennedy, and Dwight D. Eisenhower.
The coins were struck in 1975 and 1976, but all carried the dual date 1776–1976 rather than a separate 1975 date. This allowed coins minted before the anniversary year to serve as part of the same commemoration. Both copper-nickel circulation pieces and silver collector versions were produced.
The coinage is sometimes confused with a broader set of commemorative medals and tokens issued by private organizations. The official circulating Bicentennial coinage refers specifically to the quarter, half dollar, and dollar authorized by Congress and struck by the Mint.
