The baseball jersey worn by New York Yankees legend Don Larsen when he pitched the only perfect game in World Series history will soon be available for auction.

Steiner Sports Memorabilia is conducting the auction in the fall. They say a bidding war is expected for the one-of-a-kind jersey. In May, a jersey worn by Babe Ruth sold for more than $4.4 million.

Larsen pitched the perfect game during Game 5 of the World Series at Yankee Stadium on October 8, 1956. The Bronx Bombers defeated the Brooklyn Dodgers 2-0 in the game and went on to win the series in seven.

Larsen, now 82, says the game is the best thing that ever happened to him.

Steiner will announce the auction at a press conference Thursday.
