Data and price methodology

Data and price methodology

Last updated: September 4, 2026

PoBinder combines catalog data with market data to help collectors plan binders. This page explains the sources, calculations and limitations behind those numbers.

Card and set catalog

Card names, collector numbers, rarities, set metadata and most images come from TCGdex. Some older images may come from the Pokémon TCG API. PoBinder stores a local copy so pages do not depend on a live API request.

Price sources and freshness

USD data comes from TCGplayer market data through TCGCSV. EUR data comes from Cardmarket through TCGdex. Data is normally refreshed daily. Every price display names its source and latest known timestamp so delays remain visible.

What the price fields mean

TCGplayer market is a market estimate, while the Cardmarket trend is a separate EUR reference. “From” is the lowest current listing when the source supplies one. These numbers are estimates, not sale offers, appraisals or buying advice.

How set values are calculated

The base-set value sums one priced copy of each non-secret card. The master estimate sums the collectible variants recorded for each card, including secret cards. Missing prices are not treated as documented sales, so totals can be incomplete.

Factual copy and editorial limits

Set summaries are assembled from stored catalog fields and calculated statistics such as card counts and price distribution. They are not product reviews or claims of first-hand experience. The card table, source stamps and explicit calculations are the primary information.

Corrections

If a card has the wrong name, number, variant or price mapping, send the set ID, card number and a supporting source to [email protected].
