Former Texas Longhorns running back Ricky Williams sold his 1998 Heisman Trophy to a private collector back in 2014, and now the trophy is headed to auction, where it’s expected to sell for a record price.

Tallahassee, Fla. native Brian Hobbs is putting the Heisman, along with several other pieces of Williams memorabilia up at Heritage Auctions, where the crown jewel of the collection could sell for a half a million dollars in October.

Williams' Heisman carries special value because it's the last trophy that's allowed to be sold. As the listing points out, every honoree following Williams has been required to sign away the right to sell his Heisman.

The rarity of Heismans being available for sale, along with Williams' impressive 1998 season and the sheer number of Longhorns fans set up the trophy for a record day. Williams won the Doak Walker Award and Walter Camp Award in the same season, both of which are also up for auction, and he set a record with 6,592 career rushing yards that year.
