Cooper Flagg’s One-of-One Rookie Card Returns to Auction After Rookie-of-Year Season

Fanatics Collect will open bidding on September 10 for Cooper Flagg’s 2025 Topps Silver Pack SuperFractor 1/1, graded PSA 10. The card previously sold for $67,100, making this the first re-auction of the exact same one-of-one after the player’s résumé has expanded.

Flagg finished his debut with Dallas averaging 21.0 points, 6.7 rebounds and 4.5 assists over 70 games while shooting 46 % from the floor, according to NBA.com. He earned the 2025-26 NBA Rookie of the Year award and a unanimous spot on the All-Rookie First Team, becoming the second-youngest player ever to make the first team at 19 years and 112 days. The Mavericks missed the playoffs, but Flagg’s individual performance provided concrete evidence that the hype surrounding his top-draft selection was justified, shifting his cards from speculative to performance-backed assets.

Since the earlier sale, Flagg’s trophy-level cards have fetched six-figure sums. An autographed Silver Pack SuperFractor 1/1 sold for $180,000, a one-of-one Bowman Chrome Rose Gold Mojo rookie autograph reached $240,000, and a PSA 10 Topps Chrome Helix SuperFractor 1/1 commanded $197,640, according to Basketball Card Insider’s compiled sales data. These transactions, while not direct comps for the upcoming auction, illustrate the premium collectors now assign to Flagg’s unique cards.

Sports Collectors Daily reported that individual sports-card sales on eBay rose to $1.36 billion in the first half of 2026, up from $815.63 million the previous year. Basketball trophy cards remain at the top end, with a one-of-one Michael Jordan Fleer autograph selling for $504,000 in the summer, contributing to over $2.5 million in basketball-card sales that month. eBay data also showed Flagg ranked among the four most-searched basketball players on the platform during the same period, alongside Michael Jordan, Victor Wembanyama and Kobe Bryant.

The September 10 auction offers a rare market experiment: the same one-of-one card will be re-priced after a Rookie-of-Year season and a series of high-value Flagg sales. Observers will see how collectors value a card that now carries proven on-court achievement rather than pure projection, providing insight into the evolving dynamics of the sports-card hobby.
