Dallas Mavericks star Cooper Flagg, the reigning NBA Rookie of the Year, signed his one-of-one rookie debut patch autograph card on July 17, 2026. Industry experts anticipate the rare collectible could sell for millions, potentially exceeding the $1.11 million record set by Paul Skenes’ debut patch card last year.
Cooper Flagg’s One-of-One Rookie Debut Patch
The signing took place at the third annual Fanatics Fest, where ESPN’s Kevin Negandhi announced that Dallas Mavericks superstar Cooper Flagg had just completed his signature on the one-of-one rookie debut patch autograph card (RDPA). The card is a centerpiece of the upcoming 2026 Topps Chrome Update Basketball release, scheduled for August 6.
“It’s definitely the most important thing we’ve had signed at Fanatics Fest,” Mike Mahan, CEO of Fanatics Collectibles, told ESPN. “When someone signs their debut patch, it’s a big deal and Cooper Flagg — he’s into cards in a big way — appreciates what this means and how special the moment is.”

According to ESPN, this release marks a significant milestone for Fanatics, which began its exclusive NBA trading card license in October. Flagg’s debut patch is expected to be among the most valuable cards in the market, with collectors and analysts tracking its potential auction performance closely.
Market Valuation and Collector Interest
The financial stakes for such rarities have climbed steadily. While the highest price ever paid for a Flagg card currently sits at $366,000 from a March auction, the market for debut patch autograph cards has been transformed by recent high-profile sales. Geoff Wilson, founder of Sports Cards Investor, noted that the $1.11 million sale of Paul Skenes’ debut patch card in 2025 demonstrated the immense ceiling for these specific collectibles.

Wilson projected that Flagg’s one-of-one card could command even higher figures. I said, when Flagg has one and it sells, it’ll exceed that, maybe $1.5 million,
Wilson told ESPN. He added that the card is definitively his best card.
Fanatics Hobby Rip Night and Athlete Engagement
The fervor surrounding high-end trading cards was further highlighted during a recent Topps Hobby Rip Night event. The event, which spanned over 800 hobby shops globally, featured star athletes interacting with the collector community. At a shop in Indianapolis, Flagg himself participated by purchasing $7,000 worth of rookie cards featuring his former Duke teammate, Kon Knueppel, as reported by The Athletic.
This trend of athletes engaging with their own memorabilia has become a focal point for Fanatics. Mahan explained that the company’s objective is to bridge the gap between athletes and collectors through innovation.

- $1.1 million: Topps Chrome Update Paul Skenes MLB Debut Patch autographed card (sold early 2025).
- $426,000: 2020-21 Flawless NBA Logoman patch autographed one-of-one Anthony Edwards rookie card (sold June 2022).
- $252,000: 2020-21 Panini Flawless NBA Logoman patch card (Anthony Edwards, sold February 2026).
For players like Anthony Edwards, these secondary market prices often come as a surprise. When asked during the Rip Night event about the value of his most expensive card, Edwards initially guessed $100,000 before The Athletic reported he was visibly stunned to learn the actual $426,000 sale price.

Future Strategic Moves for Fanatics
Looking ahead, Fanatics is moving to expand its influence in the hobby beyond traditional sports cards. Mahan indicated that the company is investigating the trading card game (TCG) category, including titles like Magic: The Gathering and Pokemon. Additionally, Fanatics is prioritizing technological integration to improve the collector experience, including the development of a unified mobile application.
As the company continues to secure rights across multiple leagues, the potential for multisport crossovers and digital-physical hybrid experiences remains an area for future growth. Whether Flagg’s signature on the new debut patch will reach the record-breaking $5 million figure suggested by some analysts remains to be seen when the card eventually hits the open market.
