A one-of-one Cooper Flagg Topps Rookie Debut Patch Card sold for $8.04 million in a Fanatics Collect auction on Sept. 26, becoming the third-most expensive NBA card ever and the sixth-highest sports card sale in history.
The Topps Chrome Update Rookie Debut Patch Auto card, graded PSA Gem-Mint 10 for both the card and signature, featured a patch from Flagg’s jersey during his NBA debut. The auction drew 83 bids, with the final price more than doubling from $3.5 million in the final hours. The card surpassed Flagg’s previous auction record of $366,000, representing a 2,100% increase.
The sale occurred during Fanatics Collect’s September Premier Auction, which ran from Sept. 10 to Sept. 24. The bidding war concluded at 2 a.m. ET on Sept. 27, marking the highest recorded sale for a single-player basketball card.
The Card’s Unique Features and Market Impact
The Rookie Debut Patch Auto (RDPA) series, introduced by Topps in collaboration with the NBA, incorporates a game-worn patch from a rookie’s first NBA game. The patch is removed from the player’s jersey sleeve and embedded into the card, which is then signed by the athlete. This innovation has driven unprecedented demand, with Flagg’s card becoming the most sought-after in the series.
Two other RDPA cards also sold for millions during the same auction:
- Dylan Harper (San Antonio Spurs): $2.88 million
- Kon Knueppel (Charlotte Hornets): $2.16 million
The Debut Patch concept, first introduced in Major League Baseball in 2021, has since expanded to the NBA. Its rarity and the inclusion of game-used memorabilia have positioned it as one of the most innovative collectibles in the sports card market.
Flagg’s Rise and Record-Breaking Rookie Season
Cooper Flagg, the No. 1 overall pick in the 2025 NBA Draft out of Duke, was named NBA Rookie of the Year at age 19. He set an NBA record for teenagers by scoring 40 or more points four times, surpassing LeBron James’ previous record of three such performances in a season (2003-04).
Flagg made his NBA debut with the Dallas Mavericks and quickly became a focal point of the league’s rookie class. His performance, combined with his high-profile status as a former McDonald’s All-American and No. 1 high school prospect, has fueled collector interest in his memorabilia.
During a Fanatics Fest event in New York in July 2025, Flagg signed the RDPA card and discussed the significance of the moment. “I was a little nervous,” he told ESPN’s Kevin Negandhi. “I’ve signed a lot of cards, but that one was a little nerve-wracking.”
Comparing Flagg’s Card to Other Historic Sports Cards
Flagg’s $8.04 million sale places it among the most expensive sports cards ever, trailing only a few iconic pieces:
- Mickey Mantle 1952 Topps: $12.6 million (2022, Heritage Auctions)
- Shohei Ohtani 2026 Topps Chrome Gold Logoman Patch Autograph: $11 million (private sale, July 2025)
- Dual Kobe Bryant–Michael Jordan and Michael Jordan–LeBron James cards: Each sold for more than $10 million in private sales.
The Topps Rookie Debut Patch Auto series has now produced three of the top 10 most expensive basketball cards in history, signaling a shift in collector priorities toward game-worn memorabilia and rookie debut artifacts.
The Broader Sports Card Market Trends
The $8.04 million sale reflects broader trends in the sports card market, where rookie cards, patch autographs, and game-used memorabilia dominate high-value transactions. The Debut Patch series has been particularly influential, with similar cards from other sports leagues also achieving record prices.
Industry analysts note that the scarcity of 1-of-1 cards and the emotional appeal of rookie debut artifacts are driving prices upward. The Fanatics Collect auction, which facilitated the sale, has positioned itself as a key player in the high-end sports memorabilia market, leveraging exclusive partnerships with leagues and athletes.
