Cooper Flagg Rookie Card Sells for $8M

A one-of-one rookie debut patch autograph card featuring Dallas Mavericks player Cooper Flagg has sold for over $8 million USD, establishing it as the third-most expensive NBA trading card sale in history. The transaction concluded on a Friday morning after an intense bidding war on a Fanatics Collect auction, which saw 83 bids. This highly sought-after trading card, identified by the number #DPA-CF, has achieved perfect condition ratings, holding a PSA 10 GEM grade and a DNA 10 autograph grade for Flagg's signature. The card's embedded patch is directly sourced from the Dallas Mavericks jersey Flagg wore during his inaugural NBA game against the San Antonio Spurs on October 22, 2025. Cooper Flagg himself signed the card during the Fanatics Fest event in July, prior to its random insertion into a pack. The card's journey to the auction block was unconventional. It was initially pulled by Jason Williams of South Carolina during a livestreamed trading card break. Williams had purchased a spot for $515 USD in a stream hosted by RhodyBreakers, a division of Baseball Cards of Rhode Island. Following his successful pull of the one-of-one card, Williams consigned it to Fanatics Collect in August. The final sale price of $8 million USD significantly surpasses the previous record for a Cooper Flagg card, exceeding it by more than $7 million. The trading card market has seen substantial growth in recent years, with high-value sales often driven by rare, autographed, and perfectly graded rookie cards of prominent athletes. This particular sale highlights the immense collectible value placed on unique memorabilia associated with rising stars in professional sports, particularly in the NBA. The market for such items is often fueled by dedicated collectors and investors seeking assets with the potential for future appreciation. The $8 million sale places this Cooper Flagg card in elite company, trailing only a select few other iconic NBA trading cards in terms of historical sale value. The event underscores the significant financial investment and passion within the sports memorabilia collecting community.
