The ultra-rare, one-of-a-kind 2025-26 Topps Chrome Updates Basketball rookie debut patch autograph card of Dallas Mavericks star Cooper Flagg has been discovered in Rhode Island by RhodyBreakers.
The most sought-after trading card in basketball has finally turned up. Members of RhodyBreakers, operating out of the Baseball Cards of Rhode Island shop, uncovered the prized one-of-a-kind rookie card during a live-streamed pack-opening session on Monday night. The discovery brings an abrupt end to a frantic chase that captivated collectors across the sports memorabilia market before the product even hit retail shelves.
Topps officially confirmed the pull in a social media post, noting that the card features a jersey patch worn by the former Duke University star during his first-half NBA debut against the San Antonio Spurs on October 22, 2025. The card also bears Flagg’s autograph, which he applied in person during Fanatics Fest last month.
The Dallas Mavericks’ 32-Year Bounty Package
Before the card was even pulled, the Dallas Mavericks established an aggressive campaign to secure it, launching an official team bounty. The franchise structured a literal “1 of 1 for 32” trade proposal designed to lure whoever found the prized item away from a traditional public auction.
The Mavericks’ proposed compensation package covers an extensive array of high-value perks and experiences tied directly to the player’s jersey number 32:
- Two lower-level season tickets for 32 years
- A signed Cooper Flagg game-worn jersey
- A postgame photo opportunity with Flagg
- A private photoshoot alongside the NBA Rookie of the Year Trophy and the Larry O’Brien Trophy
- A private basketball experience for up to 10 guests at the arena
- A VIP travel experience for an upcoming Mavericks-Celtics road game in Boston, complete with airfare, hotel accommodations, and game tickets
Auction Projections and Seven-Figure Advances
Whoever holds the card now faces a high-stakes financial calculation: accept the Mavericks’ long-term experiential bounty or send the collectible to the auction block. A New Jersey-based memorabilia firm offered a $1.5 million cash advance to secure consignment rights, estimating the card could ultimately command up to $5 million under the hammer.
That valuation outpaces previous modern benchmarks. The current market record for a Cooper Flagg trading card stands at $366,000, while a comparable one-of-a-kind rookie card featuring Pittsburgh Pirates pitcher Paul Skenes fetched $1.11 million last year. Furthermore, the actual jersey worn by Flagg during his regular-season debut previously commanded $1 million at auction, framing the extraordinary market appetite for items tied to his stellar rookie campaign.
A Historic Rookie Campaign Backs the Card Market
The frenzy surrounding the card coincides with Flagg’s dominant entry into the professional ranks. The Maine native captured the 2025-26 NBA Rookie of the Year award after putting up averages of 21.0 points, 6.7 rebounds, and 4.5 assists per game. His debut season also featured a memorable 51-point performance against the Orlando Magic, making him the youngest player in NBA history to score 50 points in a single game.
As trading cards continue to draw major investments across the United States—with collectors spending upward of $10 million in recent years for rare pieces honoring historical stars like Michael Jordan and Kobe Bryant, alongside MLB’s Shohei Ohtani—the discovery of Flagg’s debut patch card sets a new benchmark for modern basketball collectibles.
