An INKREDIBLE Pop 1 Wilt Card! 🏀 This 1999-00 Upper Deck Retro Inkredible Level 2 Wilt Chamberlain Signed Card (#11/13) is the lone copy of this piece recorded in PSA/DNA's census reporting. This set, along with Upper Deck's Century Legends production from the same year, introduced the very first certified Chamberlain autographs available in packs. While Level 1 cards were unnumbered, the Level 2 iteration was serial-numbered out of the subject's jersey number: in the case of Chamberlain, that number is "13," making this one of the "Dipper's" scarcest signed cards. The card is graded a PSA GEM MT 10, PSA/DNA Authentic and it is available now in our historic #Goldin100 Auction.
