Cooper Flagg Rookie Card Shatters Records, Selling for $8.04 Million
The one-of-one Topps Chrome debut patch autograph card is now the most expensive basketball card featuring a single player ever.
A rare trading card of Dallas Mavericks forward Cooper Flagg has sold for $8.04 million, setting a new record for the most expensive basketball card featuring a single player. The Topps Chrome Update Rookie Debut Patch Auto 1-of-1 card, graded Gem-Mint 10 for both the card and autograph, was sold through Fanatics Collect's September Premier Auction. The auction saw 83 bids and intense competition, with the price surging from $3.5 million to over $8 million in the final hours.
This sale makes Flagg's card the sixth-most expensive trading card of all time and the third-highest NBA card sale ever. It trails only two dual logoman cards: a 2006–07 Upper Deck Exquisite Collection Dual Logoman Autographs 1-of-1 featuring Michael Jordan and LeBron James, which sold privately for $10 million, and a 2007–08 Upper Deck Exquisite Collection Dual Logoman Autographs 1-of-1 of Michael Jordan and Kobe Bryant, which fetched $12.9 million in August 2025.
The card features a patch worn by Flagg during his NBA debut on October 22, 2025, against the San Antonio Spurs. The Debut Patch concept, introduced in Major League Baseball in 2021, involves incorporating a game-worn jersey patch and an autograph into a trading card. A similar card for Paul Skenes sold for $1.11 million.
Flagg, the reigning NBA Rookie of the Year and a former No. 1 overall high school prospect, has seen his sports card market boom since his emergence at Duke. The card was pulled during a live stream break by Rhody Breakers in Rhode Island and belonged to collector Jason Williams of South Carolina, who acquired his spot in the break for $515.
Despite the record-breaking sale, some in the hobby question the investment value, suggesting that proven legends or vintage cards might offer more stable returns. However, the sale contributes to a broader trend of increasing interest in the sports card market, with other high-value sales including Dylan Harper's card for $2.88 million and Kon Knueppel's for $2.34 million. The $8.04 million sale represents a significant payday for Williams and highlights the growing financial appeal of collectibles.
