2025-26 Topps Definitive Collection Basketball Checklist

2025-26 Topps Definitive Collection Basketball is a high-end release built entirely from autographs and memorabilia, with no standard base set, released September 17, 2026. Nearly every subset shares a short parallel ladder of Orange /25, Pink /15, Black /10, Red /5, Blue /2 and Gold 1/1, and the checklist leans heavily on the 2025 rookie class alongside retired legends.

Key rookies and legends

Cooper Flagg, the No. 1 pick in the 2025 NBA Draft, appears across Rookie Patch Autographs, Rookie Defining Games and multiple Dual and Triple Rookie Autographs alongside Dylan Harper, Ace Bailey and Kon Knueppel. Cedric Coward, Asa Newell, Collin Murray-Boyles, Egor Dëmin and Khaman Maluach round out the class. The Legendary Autograph Collection includes Larry Bird, Magic Johnson, Kareem Abdul-Jabbar, Hakeem Olajuwon, Dirk Nowitzki and Oscar Robertson.

Grading considerations

Rookie Patch Autographs, the Triple Rookie Autographs and Nameplate relics are among the cards collectors commonly consider for grading. Thick patch and nameplate cards need larger holders, and framed autographs should be checked for corner and edge dings on the frame. See our grading scale.
