Gastly card prices

Each card has one vote: one fixed finish per TCGplayer product, chosen in the order Holofoil, Normal, Reverse Holofoil, then other finishes alphabetically. We compare the exact same finish on both dates. Starting Market Price must be at least $2; both prices must be positive and pass the listing-summary reliability checks. The wider Pokémon benchmark uses the same rules and counts each product once. Species, forms and team membership follow this page's catalogue.

Cheaper and expensive groups are fixed by prices at the start of the window, before any rise or fall. Group sizes round down; equal-price ties use product ID. A comparison is omitted if the resulting price ranges overlap. Their figures are median card changes, not the return of a purchasable basket. A price-change count is not sales volume. Card forecasts remain on their individual reports; this brief describes observed history.

Coverage is the number of catalogue products with a usable matched price pair, not a claim about every physical card or sale. At least five matches are required for a market verdict; price tiers require twelve matches and distinct starting-price groups.

Outside this matched 90-day cohort: 1 failing the end-date pricing check; 2 failing the start-date pricing check; 29 starting below $2.
