The 1984 Summer Olympic torch that Bruce Jenner carried through Lake Tahoe, Nevada, is going on auction where it could fetch $20,000 or more.

It's the first major piece of Jenner memorabilia on the block since the winner of the 1976 Olympic decathlon gold medal-winner became Caitlyn Jenner.

The 61-centimeter torch, featuring a brass finish and leather handle, is being offered by Heritage Auctions at its Platinum Night Sports Auction in Chicago on July 30. The seller is Bob Lorsch, a Los Angeles philanthropist and entrepreneur who orchestrated the Tahoe leg of the torch relay and secured Jenner's participation.
