A Record Bid in the Final Hours
A rookie card of Dallas Mavericks forward Cooper Flagg sold for $8.04 million at auction on Friday, the highest price ever paid for a single basketball card. The one-of-one 2026 Topps Chrome Updates NBA Debut Patch autograph card went through Fanatics Collect’s September Premier Auction, which opened bidding on September 10 and closed early Friday morning after 83 total bids.
The price barely resembled where it started. Bidding sat at $3.5 million before a late surge pushed it past $8 million in the auction’s final hours, according to Card Ladder and The Athletic. The card itself was pulled from a pack in Rhode Island in August.
Cards like this one command those numbers because they stack three scarce elements into a single piece of cardboard: an on-card autograph, a swatch of game-worn material, and true one-of-one status, meaning no second copy exists anywhere. That combination is what collectors were fighting over during the final bidding war.

Only One Sports Card Has Sold for More
Flagg’s card is now the fifth-highest price ever paid for a publicly known sports card sale, sitting behind a group of trading cards that includes the T206 Honus Wagner baseball card, the hobby’s long-standing benchmark, which sold for $7.25 million in 2022. Flagg’s card cleared that mark by nearly $800,000, and it stands as the first basketball card to enter that upper tier of the market.
The number reflects how quickly the market has moved on Flagg. He was the No. 1 overall pick in the 2025 NBA Draft, and last season he averaged 21.0 points, 6.7 rebounds and 4.5 assists across 70 games for Dallas on his way to being named the league’s Rookie of the Year. Card collectors have treated few rookies with this kind of urgency since LeBron James entered the league two decades ago.
What It Signals for the Mavericks
For Dallas, the sale is a reminder of the asset it is building around. Flagg heads into his second season as the face of the franchise, and with the Mavericks reshaping their roster this offseason, his rookie-year production already carries the kind of collector premium usually reserved for established stars. The next test comes on the court, when the regular season opens next month.
