How this is built. Market price is the TCGplayer market price carried in InkSight's daily snapshot of August 30, 2026. 7D change compares the real snapshots of August 24, 2026 and August 30, 2026; 30D change compares the real snapshots of August 1, 2026 and August 30, 2026. Cards with no real snapshot on a baseline date show “—”: nothing here is interpolated or estimated. Rankings cover singles only — sealed products, presale-priced rows, serialised one-of-one prints and prices flagged as market outliers are excluded.
