Perhaps the most confusing set we have ever encountered, the 1980-81 Topps Basketball issue consists of 264 numbered cards on three-card, perforated panels. Topps created two different print sheets, changing the panels so that a complete set of panels includes 176 different three-panel impossible-to-sort cards. Presented here is a 171-card partial set, missing just five for completion, including the Bird/Erving/Johnson card that is key to the set. The cards grade roughly 8% NM or better, 30% EX/MT, 47% EX, 14% VG/EX, and a few lesser. We submitted three cards to CGC for evaluation, which graded as follows: Johnson /Bird/Sikma: CGC NM-MT+ 8.5; Cheeks/Johnson/Boone: CGC NM/MT 8; Bridgeman/Bird/Brewer: CGC NM 7. This is an original owner collection, pulled directly from packs, and despite that there are size variances that render some of them a bit small. 171 cards total.
