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?

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.

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.
