Which image was on the reverse of the 1976 United States Bicentennial dollar?

The reverse of the 1976 United States Bicentennial dollar showed the Liberty Bell superimposed against the Moon.

The coin was a redesigned Eisenhower dollar issued for the bicentennial of American independence. Dennis R. Williams submitted the winning design in a nationwide competition. The composition combined the Liberty Bell, a symbol associated with the American Revolution, with the Moon, recalling the United States’ space achievements.

The Bicentennial dollar was one of three circulating coins with temporary reverse designs. The quarter featured a colonial drummer, and the Kennedy half dollar depicted Independence Hall. Each coin retained its normal obverse portrait but displayed the dual date 1776–1976.

Williams was only 21 when his design was selected, making him the youngest person to design a U.S. coin up to that time. The dollar was struck in both copper-nickel clad versions for circulation and silver-clad versions for collectors. Its special design was used only for the 1975–1976 bicentennial issue.
