Just looking at the auction site. He auctioned his player contracts.

In 1959 he was paid $8,300.
In 1968 he was paid $26,000.

Some interesting things. Letters from Lombardi, Emlen Tunnel and Jackie Robinson; his handwritten notes on the game plan for Super Bowl-I; lots of game-worn jerseys, some shoes and a beat-up helmet; quite a few signed game balls, his Packer HOF ring and plaque, various sweaters, including the one for the College All Star game.
