Product Details

Black Diamond is a trading card brand by Upper Deck and the Quad Diamond tier relies on four diamond symbols instead of printed serial numbers on the front to designate their tier. Tier 1: Single Diamond (Common/Base). Tier 2: Double Diamond (Uncommon/Short Print). Tier 3: Triple Diamond (Rare/Super Short Print). Tier 4: Quadruple Diamond (Ultra Rare/Case Hit level). Why Quadruple Diamonds Are Rarer: Print Runs: In classic sets, Triple Diamond cards were typically serial-numbered to 1,500 copies. By comparison, Quadruple Diamond cards were strictly limited to 100 or 150 copies. In 2004-05 Upper Deck Black Diamond Basketball, Quad Diamond cards are not serial-numbered because they function as ultra-short-printed tier level rather than limited parallel editions. Instead of stamping a serial number (like /150 or /100) on Quad Diamonds, Upper Deck controlled their scarcity strictly through pull rates in hobby packs.
