Former Green Bay Packers offensive lineman Jerry Kramer is putting his ring from the first Super Bowl up for auction.

Green Bay Press Gazette Media reports the ring is one of 60 items Kramer is selling through Heritage Auctions. The other items include Kramer's game-used jersey from Super Bowl I and his Packers Hall of Fame ring.

Kramer, who will turn 80 this month, played with Green Bay in the 1960s. He said he is selling the items to clear his house of things he doesn't need and plans to use the money to create a college fund for his five grandchildren.

"There was an awful lot of stuff in there that I'd forgotten about," Kramer said.

The newspaper reports that a conservative estimate has the ring selling for $100,000 during the Feb. 20 auction.

Kramer declined to sell his Super Bowl II ring, saying it means too much to him.

In a separate auction being held this month, quarterback Mark Rypien's Super Bowl XXII ring had a high bid of $17,000 as of Thursday morning, according to The Washington Post. Rypien did not play in that Super Bowl. He started for the Washington Redskins and won Super Bowl XXVI four years later.
