What is a centennial Eisenhower silver dollar worth with an eagle on the back or bell moon back?

The Eisenhower silver dollar was minted from 1971 to 1978, and there is no such thing as a "centennial Eisenhower silver dollar".

The reverse (tails) of the Eisenhower dollar features an image of an astronaut exploring the moon's surface with a large eagle landing in the background, holding an olive branch in its claws. This design is often referred to as the "eagle landing" or "eagle moon landing" reverse.
