A major piece of sports memorabilia is going up for grabs, and it's gonna cost a pretty penny.

The Chicago Bulls jersey Michael Jordan wore during the first game of the 1998 NBA Finals is being auctioned off by Sotheby's.

Jordan and the Bulls beat the Utah Jazz in the championship that season four games to two.

It was also the last championship Jordan won with Chicago.

The auction house calls the jersey "one of the most significant items from Michael Jordan's career."

It's expected to reach up to $5 million, which Sotheby's says would make it the most ever spent on an item related to the iconic athlete.

Bidding begins on Sept. 6 and ends on Sept. 14.
