- Cooper Flagg signed his one-of-one rookie debut patch autograph (RDPA) card at the third annual Fanatics Fest, which Fanatics Collectibles CEO Mike Mahan called "the most important thing we've had signed at Fanatics Fest."
- The card appears in 2026 Topps Chrome Update Basketball (releasing Aug. 6) — Fanatics' first basketball set under its exclusive NBA trading card license that began in October — with RDPA cards of Kon Knueppel, Dylan Harper, Ace Bailey, and Derik Queen also inserted as redemption cards.
- Flagg's debut-game jersey — the source garment for the card's patch — sold for $1 million at NBA Auctions in February, a then-record, while the current high for any Flagg card stands at $366,000 from a March auction.
- Geoff Wilson, founder of Sports Cards Investor, predicts Flagg's RDPA could hit $1.5 million and potentially $5 million, pointing to Paul Skenes' $1.11 million RDPA sale last year as the precedent that "opened collectors up" to the category.
- Fanatics Collectibles CEO Mahan outlined next moves: expansion into trading card games like Magic: The Gathering and Pokémon, multisport crossover releases, and a centralized collector app to consolidate the hobby experience.
- Athletes are now actively pursuing their own rookie debut patch autograph cards — what Mahan called "an iconic symbol" — even when they aren't hobby collectors themselves.
- Asked by ESPN's Kevin Negandhi if he'd bid on his own card once pulled, Flagg quipped: "I might have to wait until I get my second contract, but maybe eventually."
Why it matters: The Flagg RDPA sets a new price ceiling for basketball cards — potentially dwarfing the $1.11 million Skenes baseball RDPA — at a moment when Fanatics holds sole NBA card rights and athletes themselves are competing for these patches as trophy collectibles.
