Rhode Island Uncovers Cooper Flagg’s 1-of-1 NBA rookie card
A rare 1-of-1 Cooper Flagg NBA rookie card with a jersey-patch from his Mavericks debut and Flagg’s signature was found in Rhode Island during a live stream by RhodyBreakers. Released in the 2026 Topps Chrome Update Basketball set and bolstered by Flagg’s Rookie of the Year recognition for 2025-26, the card has drawn global attention and the Mavericks have offered an extravagant “1 of 1 for 32” package (tickets, a signed jersey, photos, a VIP tour, etc.) in an effort to acquire it.
