NFL's Ken Stabler's Solid Gold 84 Ounce Belt Buckle Up For Grabs!

Interested in having 84 OUNCES of solid gold hanging around your crotch???

You're in luck ... because Ken Stabler's legendary "Hickok Belt" just hit the auction block.

The belts were given away to the top U.S. athlete from 1950 to 1976 -- and feature 84 ounces of solid gold with a 3 carat diamond, 3 carat ruby, 3 carat sapphire and 26 diamond chips.

Stabler was the LAST person to win the belt -- following his spectacular '76 season in which he led the Oakland Raiders to a Super Bowl victory.

Previous winners include Muhammad Ali, O.J. Simpson, Joe Namath, Jim Brown and Sandy Koufax (he won twice).

Stabler's belt was displayed at the University of Alabama for years -- but now, it's up for grabs through Pristine Auction.

Starting bid -- $20,000 ... but the auction house believes the materials are worth $180,000 alone!
