Suck at football but still wanna own your own Heisman Trophy?? Better have NEARLY HALF A MILLION DOLLARS laying around.
The 1937 trophy -- won by Yale's Clint Frank -- is hitting the Heritage Auctions block ... and experts tell us it's expected to go for over $400,000.
The 25-pound award was only the third one ever given out ... but Frank's family is ready to part ways with it -- for the right price.
