Set value is one of each card at its market price — 110 of 131 cards in this set carry one. It is what the singles would cost at today’s prices, not an appraisal, and it excludes sealed product. The typical card is the median, because one chase card pulls an average far away from what most of the set is worth.

Weekly chain-linked index. Each step compares only cards priced in BOTH of the two weeks, so items appearing or delisting cannot move the line — 10.6% of a fixed basket went dark over the last eleven months, and a level computed over whoever reported today would follow that instead of prices. An item must clear $5 in both weeks of a step to count: without a floor, penny rounding dominates. The line is the longest unbroken run of weeks with enough matched pairs — a week too thin to measure truncates it rather than being bridged over. Scoped to this set, using the same construction as the market index. How this is built.
