Two-time All-Star San Antonio Spurs center Victor Wembanyama obviously boasts one of the most collected trading cards this season. But so does another, surprising Spurs teammate.
And no, it’s not the 7-foot-4 Frenchman’s fellow 2026 All-Star, point guard De’Aaron Fox.
Per the top sports card grader, Professional Sports Authenticator (PSA), Castle’s 2024 Mosaic debut card ranks as the third-most collected U.S. player’s card during the 2025-26 season to this point.
San Antonio Rising Star Becoming Mr. Popularity?
The reigning Rookie of the Year has notched over 10,900 cards graded this year.
Stateside, Castle trails only WNBA All-Star point guard Caitlin Clark of the Indiana Fever’s 28,600-plus graded cards, Dallas Mavericks rookie power forward Cooper Flagg’s 23,800-plus graded cards (although his one-and-done Duke card is the most popular), 22-time All-Star Los Angeles Lakers forward LeBron James’ 22,500-plus cards graded and 12-time All-Star Golden State Warriors point guard Stephen Curry’s 14,100-plus cards graded among U.S. NBA talent.
Among international basketball talent, Wembanyama leads the way with 23,700-plus cards graded.
Castle has looked like a fringe All-Star this season, even if he didn’t get a nod alongside Wembanyama and Fox. He may, however, still have a shot at joining Wembanyama on an All-Defensive Team honor in the spring.
Stephon Castle 2024 Mosaic Rookie Card
Across his 44 healthy bouts for the 38-16 Spurs this year, Castle has been averaging 16.5 points on .464/.288/.722 shooting splits, 7.0 dimes, 5.0 boards, and 1.3 swipes a night.
The 21-year-old University of Connecticut product is already a lethal two-way menace. Clearly, collectors project that he could become a perpetual All-NBA honor down the road.
