Data & pricing
Prices are the heart of CollectHolo, so here is exactly where they come from and how we work them out. We show real market values, not guesses.
Where prices come from
We pull from the marketplaces and auction houses collectors actually use:
- Raw (ungraded) cards: TCGplayer and Cardmarket. English and Japanese are priced from both; German, Italian, Korean, and Simplified Chinese are priced from Cardmarket.
- Graded cards: sold listings from eBay, completed auctions from Goldin, and inventory from Fanatics, across PSA, BGS, and CGC, alongside PSA population data.
- Sealed products: TCGplayer, Cardmarket, and eBay, plus Amazon where available.
How prices are calculated
- Graded cards lead with what has actually sold, since real sales are the most reliable signal of value.
- Raw cards and sealed products use the lowest current asking price.
- Variant and condition aware: prices match a card's exact variant (Holofoil, Reverse Holofoil, 1st Edition, and so on), with Near Mint as the baseline for raw cards.
- Open auctions never count as a sale until they actually close.
How often we update
- Exchange rates: every 12 hours, so converted prices stay current.
- Graded prices: daily.
- Raw card and sealed product prices: daily.
- PSA population data: daily.
Languages and markets
Important: we show real local prices for every language and never fall back to a US price. German, Italian, Korean, and Simplified Chinese cards are priced from their own market, not converted from an English card, so you see what that exact card actually trades for in that language.
Each language is priced from the market where collectors actually buy it:
- English: TCGplayer and Cardmarket
- German: Cardmarket
- Italian: Cardmarket
- Korean: Cardmarket
- Simplified Chinese: Cardmarket
- Japanese: TCGplayer and Cardmarket
German, Italian, Korean, and Simplified Chinese are priced only from Cardmarket, so they never show a US TCGplayer price. If a value is not yet available for one of them, you will see a small warning marker instead of a misleading number. We would rather show no price than the wrong one.
