It became the highest price paid for a game-used college football jersey in an Internet auction, surpassing the price paid Friday by the winning bidder of a game-used Georgia jersey of Frank Sinkwich, who won the Heisman Trophy in 1942. That jersey sold for $31,070.
Going into Monday, bidding for the Fournette jersey had reached $40,000, but at least two people were willing to pay more than double that amount by the auction's end.
The funds will be earmarked for victims of the flood in South Carolina, which forced the Gamecocks to move their Oct. 10 home game to Baton Rouge.
Fournette, who leads the nation in rushing with 1,383 yards, ran for 158 yards and a touchdown in LSU's 45-24 win over the Gamecocks.
The auction, which was approved by the NCAA and took place on LSU's athletics website, also included signed helmets by the game's head coaches, Steve Spurrier and Les Miles.
The record for the highest-priced college jersey at auction was one worn by Tim Tebow during his junior season with the Florida Gators. It sold at a charity banquet for $250,000, and the winning bidder gave the jersey back to Tebow.
Christian Laettner's Duke jersey worn during "The Shot" holds the record for any college jersey sold on the Internet. That sold for $119,500 last year.
