American Bob Beamon, 77, decided to sell his legendary gold medal won in 1968 at the Mexico Olympics after his jump to 8.90. In a booming sports memorabilia market, Christie's experts had valued this medal at between 400,000 and $600,000.

The historic jump at the 1968 Mexico Olympics reached 8. 90 m, a world record until the Tokyo World Championships in 1991. “It’s time for me to pass it on,” said the 77-year-old former athlete, before the auction.
