Cooper Flagg’s One-of-One Rookie Debut Patch Autograph Card Debuts at Fanatics Fest

On July 17, during the third annual Fanatics Fest in New York City, Dallas Mavericks rookie of the year Cooper Flagg signed a one-of-one Rookie Debut Patch Autograph (RDPA) card. The card, featuring a patch from Flagg’s first regular-season game, was displayed in a glass case at the Javits Center and will remain on view through the festival, which runs July 16-19. The RDPA will be inserted as a redemption card in the 2026 Topps Chrome Update Basketball set, scheduled for release on August 6, 2026, alongside similar cards for teammates Kon Knueppel, Dylan Harper, Ace Bailey and Derik Queen.

Industry observers note that the debut-patch concept ties the collectible directly to a player’s first NBA appearance, making the item unique. Promotional material suggests the card could eventually fetch “low-to-mid seven figures,” though no independent appraisal or public sale has confirmed a price. Flagg’s rookie season—averaging 21.0 points, 6.7 rebounds, 4.5 assists and 1.2 steals, and becoming the first rookie since Michael Jordan (1984-85) to lead his team in those four categories—has driven heightened collector interest.

Mike Mahan, CEO of Fanatics Collectibles, described the signing as “the most important thing we’ve had signed at Fanatics Fest” and emphasized the company’s goal to “improve the collector experience every day” with a forthcoming all-in-one app. ESPN’s Kevin Negandhi highlighted Flagg’s status as a “superstar” and asked whether the player might purchase the card later. Sports-card investor Geoff Wilson linked Flagg’s card to the market surge sparked by Paul Skenes’ $1.11 million sale, predicting that Flagg’s card could exceed $5 million.

The projected seven-figure value remains speculative; the card has not yet entered the secondary market, and its eventual price will depend on grading, buyer identity, and market conditions. No independent appraisal has been published, leaving the exact future worth uncertain.
