How this estimate works

Every figure here is an estimate from a disclosed model, not a sale price. Estimated graded value = the card's raw Cardmarket trend price x a published, era-based grade-uplift rule of thumb, it is NOT an eBay/auction comp, and Foilio does not use any marketplace sold-listing data. Grading fees are real 2026 PSA figures (in USD, shown converted to EUR at a fixed rate); EU sellers also pay shipping and import VAT on top. Outcomes vary card to card. Informational only, not financial advice. Confirm condition and live prices before submitting anything.

Raw prices: Cardmarket via pokemontcg.io (trend price, EUR). Population & cert (where shown): official PSA Public API. Foilio is not affiliated with PSA or Cardmarket. Model v1.1.0, reviewed 2026-06-17.
