(CNN) A high school basketball jersey once worn by former President Barack Obama is up for auction.

The white jersey, which says "Punahou" and "23" on the front in blue lettering, is faded and stained but still expected to fetch a pretty penny. The starting bid was $25,000, but Heritage Auctions, which is selling the jersey, expects the garment to sell for at least $100,000 when bidding ends August 17.

The future 44th president wore the jersey in his senior year at Punahou School in Honolulu, where he was a member of the 1979 Hawaii State Champion boys' varsity basketball team.

Obama wore the jersey during his senior year at Punahou School in Hawaii.

The jersey belongs to another Punahou alum, Peter Noble, who was three years younger than Obama. Noble wore the 23 jersey while playing for the junior varsity team.

The jersey comes with Noble's yearbook from Obama's senior year, according to Heritage Auctions.
