The jersey Babe Ruth was wearing during one of the most iconic moments of his career is going up for auction, and it could sell for a record-breaking amount of money.

Ruth’s road grey New York Yankees jersey with the number 3 on the back will be put up for auction later this month — the same jersey he was wearing when he purportedly “called his shot” against the Chicago Cubs during the 1932 World Series.

And if the estimates of Heritage Auctions, the auction house facilitating the sale, come to fruition, the jersey could garner bids of more than $30 million — a figure that would smash the world record for the most expensive game-worn sports jersey ever sold.

“Ruth’s World Series jersey is the most significant piece of American sports memorabilia to be offered at auction in decades,” Chris Ivy, Director of Sports Auctions at Heritage said in a press release. “Given its history, its mythology, we expect that when the final bid is placed, it will hold the record as the most expensive sports collectible ever to cross the auction block.”

The myth of the “Called Shot” lives on because it happened in a time before baseball games were televised. Fans relied on newspaper reports to find out what happened at road games. According to Heritage Auctions, it was newspaper editor Joe Williams who wrote the headline crediting Ruth with calling his shot, like one would in billiards, when he gestured toward center field in the fifth inning and then hit a home run to that same part of the stadium on the next pitch.
