In the 1976 United States Bicentennial coinage, the half dollar featured Independence Hall on its reverse.
The coin was the Kennedy half dollar, whose reverse was redesigned for the Bicentennial by artist Seth G. Huntington. Independence Hall in Philadelphia was chosen because delegates debated and adopted foundational documents there, including the Declaration of Independence and the United States Constitution.
The Bicentennial half dollar was part of a three-coin circulating commemorative series. The other coins were the Washington quarter and Eisenhower dollar. All three retained their usual obverse portraits but carried the dual date 1776–1976.
A common mix-up is confusing the half dollar’s Independence Hall design with the quarter’s image of a colonial drummer or the dollar’s Liberty Bell and Moon design. The special reverse designs were temporary: the Mint returned to the regular reverse designs after the Bicentennial issue.
