Who designed the reverse of the 1976 U.S. Bicentennial Eisenhower dollar?

Dennis R. Williams designed the reverse of the 1976 U.S. Bicentennial Eisenhower dollar.

Williams was a 22-year-old art student when his design was selected through a nationwide competition. His winning concept showed the Liberty Bell superimposed against the Moon, combining a symbol of the American Revolution with an image connected to the nation’s space achievements.

U.S. Mint Chief Sculptor-Engraver Frank Gasparro later modified the design for production. The Bicentennial dollar was issued with the dual date 1776–1976 and used the special reverse only for the anniversary period.

The designer is often confused with Gasparro because Gasparro prepared the final dies and made changes to the design. Williams, however, submitted the winning original design and became the youngest person to that point to design a U.S. coin. The dollar was one of three circulating Bicentennial coins, alongside the quarter and half dollar.
