What two images were combined on the reverse of the Eisenhower dollar in the United States Bicentennial coinage?

The reverse of the Eisenhower dollar in the United States Bicentennial coinage combined the Liberty Bell and the Moon.

The United States Mint selected three special reverse designs for coins marking the 200th anniversary of American independence. The dollar showed the Liberty Bell superimposed on the Moon, creating a composition that connected the nation’s revolutionary past with the era of space exploration.

The design was used on Eisenhower dollars struck for circulation and for collectors. Like the Bicentennial quarter and half dollar, the coin carried the dual date 1776–1976. The temporary design replaced the usual eagle-and-Moon reverse associated with the Eisenhower dollar.

The three Bicentennial reverses were deliberately distinct. A Colonial drummer appeared on the quarter, Independence Hall appeared on the half dollar, and the Liberty Bell–Moon composition appeared on the dollar. All three denominations were issued in copper-nickel versions, with special silver-clad versions also produced for collectors.
