In 1935, the United States stopped the minting of dollar coins. Several attempts were made in the following decades to revive their issue, but they all failed. At the end of the 1960s, when America was torn as a nation by race riots and the war in Vietnam, the Congress came up with the idea of a new dollar coin once again. The new coin was to serve as a symbol of identification for the American people. The obverse of the new dollar depicted the former president Dwight D. Eisenhower, during whose term in office (1953-1961) the American space agency NASA had been founded. The reverse featured a rendition of America's pride: the space flight of Apollo XI and the first landing of humans on the moon. "The eagle has landed," had the astronaut Neil Armstrong reported then.
