The auction house expects bids to be in excess of $10 million, with the sale poised to becoming one of the “most valuable collection of sports memorabilia at auction,” it said.

If achieved, the price for the set would surpass a jersey worn by Michael Jordan in Game 1 of the 1998 NBA Final from his famous “Last Dance” season, which sold for $10.1 million at Sotheby’s last year. That shirt currently holds the world record title of being the “most valuable item of sports memorabilia ever sold at auction,” according to the auction house.

The current record for a match-worn item of soccer memorabilia is held by legend Diego Maradona and his “Hand of God” shirt that Sotheby’s sold for $9.3 million last year. Bids were initially expected to range from $5 million to $7 million, perhaps signaling that Messi’s jersey prices could go higher.

“The sale of these six shirts stands as a monumental occasion in auction history, offering fans and collectors a connection to Messi’s crowning achievement,” said Brahm Wachter, head of modern collectibles for Sotheby’s, in a release. “It is an honor for Sotheby’s to present and exhibit these invaluable collectables to the public, which encapsulate the sheer brilliance of a player who has redefined the boundaries of football excellence.”

To date, the most expensive match-worn Messi jersey sold at auction was for $450,000 last year, which he wore during the 2017 El Clásico, a tense battle between his former team of FC Barcelona against Cristiano Ronaldo’s Real Madrid. Messi’s last-minute goal, the 500th of his career, was the match winner.

The online auction for Messi’s jerseys runs from November 30 to December 14 and will be displayed during that time in a free exhibition at Sotheby’s gallery in New York.

Sotheby’s added that the Messi auction comes during a “vigorous market for sports memorabilia and collectibles, fueled by the property and unique experiences it offers.” Similar auctions, including jerseys from NFL great Tom Brady and the late NBA player Kobe Bryant, are luring in younger bidders too, half of them being under 40 years old, with more than half entirely new to its sales, the company said.

Messi, 36, joined MLS team Inter Miami earlier this year, ending a roughly two-decade long stint playing for European teams, notably Barcelona and most recently Paris Saint-Germain. His appearances sent MLS ticket prices skyrocketing and fans had trouble getting their hands on replica jerseys for several months.

Last year in Qatar, Messi helped his country of Argentina win its third FIFA World Cup title (and his first) by beating France via a penalty shootout in one of the most thrilling finals in tournament history. Adidas said that his jerseys and Argentina team kits quickly sold out.
