Cooper Flagg rookie card returns to auction block on September 10

The 2025 Topps Silver Pack SuperFractor 1/1 rookie card featuring Dallas Mavericks forward Cooper Flagg will return to auction at Fanatics Collect starting September 10. The card, graded PSA 10, previously sold for $67,100 in March. Its market value now faces a new assessment following Flagg’s debut season, during which he averaged 21.0 points, 6.7 rebounds, and 4.5 assists. Flagg earned the 2025-26 NBA Rookie of the Year award and was selected to the NBA All-Rookie First Team despite the Mavericks missing the playoffs with a 26-56 record. Other one-of-one cards featuring Flagg have reached six-figure sales in recent months, providing a benchmark for this upcoming transaction. The team has since installed Dusty May as head coach to manage Flagg's expanding role on the court.
