The double date 1776–1976 appeared on United States Bicentennial coins minted in 1975 and 1976.
The special circulating commemorative set included a quarter, a Kennedy half dollar, and an Eisenhower dollar. Each used a temporary reverse design and displayed the paired years rather than a single year on the obverse.
The coins were authorized to mark the 200th anniversary of American independence. Although some pieces were struck in 1975 and others in 1976, all carried the same 1776–1976 date. This makes the coins distinctive among ordinary United States circulation issues.
The quarter showed a colonial drummer, the half dollar featured Independence Hall, and the dollar depicted the Liberty Bell superimposed on the Moon. The designs are sometimes mistaken for ordinary commemorative coins that were not intended for circulation, but these three denominations were made for public use as well as for collectors.
