2007-08 Topps Chrome Refractors #131 Kevin Durant Rookie 1203/1499 BGS GEM MINT 9.5. Chrome Refractors are perhaps Topps' most popular inserts regardless of sport or subject, and this KD rookie example stands out as does the two-time NBA Finals MVP himself. Exceptional sub-grades include: Centering 9.5, Corners 9, Edges 9.5, Surface 9.5; as close to perfection as the four-time scoring champ and 11-time All-Star himself, and almost as popular.
