5 Dollars (XXVI Olympiad Stadium)

The 1995 $5 Olympic Stadium Gold

In 1995 the U.S. Mint released this tiny gold coin to honor the Atlanta Olympics. It was part of the largest commemorative coin program in American history — and that turned out to be the problem. So few people bought it that today it ranks among the rarest modern U.S. gold coins, not because it's old, but because almost nobody wanted it when it was new.
