Someone just forked out a whole lot of cash to purchase Cooper Flagg’s rookie jersey.
The jersey worn by the Dallas Mavericks star during his very first NBA game sold privately for a staggering $1 million, Sotheby’s confirmed to The Sporting News in a press release on Thursday, Feb. 19.
Flagg wore the jersey during the first half of his highly anticipated NBA debut against the San Antonio Spurs on October 22, 2025.
It’s officially the highest recorded price for any of Flagg’s collectibles to date and also broke a new record for the highest price ever achieved for a jersey sold through NBA Auctions.
There are several moments that made Flagg’s debut jersey so valuable.
For starters, he has a habit of breaking records.
After being selected first overall in the 2025 draft following an impressive run at Duke, the NBA rookie has continued to go viral for his poise on and off the court. Since being drafted, Flagg’s become the youngest player in the league to score 40 points in a single game and has recorded double-digit assists.
