Cooper Flagg's rookie debut patch card sold for $8.04 million in Fanatics Collect's September Premier Auction, setting a record for the most expensive basketball card sale featuring a single player. The card received 83 bids during the two-week auction, with a late bidding war pushing the price from $3.5 million to $8.04 million early Friday morning. The sale surpassed the previous record for a Cooper Flagg card of $366,000 and is the third-most-expensive NBA card sale ever, trailing only dual card sales of LeBron James-Michael Jordan and Kobe Bryant-Jordan.\n\nThe card was pulled in a break by Rhody Breakers in Rhode Island and belonged to collector Jason Williams of South Carolina, who put it up for auction with Fanatics Collect.

In the same auction, Dylan Harper's debut patch sold for $2.88 million, and Kon Knueppel's sold for $2.34 million. These three cards rank among the most expensive debut patch sales of all time.\n\nThis is the first class of NBA debut patch cards where each rookie drafted in the 2025 class wore a patch in his first game, which was removed at the game's conclusion, put into a card, and signed by the player. Flagg, 19, made his NBA debut with the Dallas Mavericks on Oct. 22, recording 10 points and 10 rebounds in a loss to the Spurs.
