METHOD & DATA
How the market cap number is built
Market cap is the current PSA 10 reference price multiplied by the verified PSA 10 population, recalculated on every daily update.
Reference price
The most recent completed PSA 10 sale captured inside CardZ Marketcap tracked coverage. Lots are unitised down to a single card, and a sale priced far outside its own recent range is rejected in favour of the next most recent one.
Population
The verified PSA 10 population for that exact printing — language, set, collector number and parallel are never merged across printings.
Gaps
A card with insufficient data coverage in the window is marked as accumulating rather than being given a filled-in number. A missing value stays missing, never zero.
