Cooper Flagg rookie card discovery sparks massive auction potential

A unique, one-of-a-kind Cooper Flagg rookie trading card was discovered during a live stream by RhodyBreakers at a card shop in Rhode Island. The card, part of the 2026 Topps Chrome Update Basketball set, features an autograph from the Dallas Mavericks star and a jersey patch from his NBA debut.

The finder now faces a significant choice between a high-value auction or a specialized compensation package offered by the Dallas Mavericks. The team’s “1 of 1 for 32” offer includes two premium lower-level season tickets for the next 32 years, a signed game-worn jersey, a postgame photo with Flagg, and various VIP experiences, including a trip to a game against the Boston Celtics.

Market experts suggest the card could be worth millions of dollars at auction, noting that a similar card for MLB pitcher Paul Skenes sold for $1.11 million last year. Additionally, a New Jersey-based collectibles company has reportedly offered a $1.5 million cash advance for the rights to auction the card, with estimates suggesting it could eventually fetch up to $5 million.
