Frequently Asked Questions

FlipFoundry is a free research tool for sports cards and Pokémon cards. It has two tools. In Listings, you search a card and see live eBay listings next to a market value from a price guide. In FlipCheck, you paste an eBay sports-card or Pokémon listing link and see the card's value, what it's worth at each grade, a verdict on the asking price, and a suggested offer.

Yes. FlipFoundry is free to use. It is funded by the eBay Partner Network: when you buy through an eBay link on FlipFoundry, we may earn a commission, at no extra cost to you. To keep FlipFoundry free, there are daily limits on searches and checks from each network.

From a third-party price guide, for the same card, grader, and grade — not from what sellers are asking. Values are estimates, not guaranteed prices. When we don't have a value for a card, we say so instead of guessing.

Type a player or a specific card into Listings. A player search shows their cards listed on eBay right now. A specific card shows its live eBay listings next to a market value. If your search matches more than one version of the card, pick the one you mean to see its value.

Many cards come in several versions — base, refractors, numbered parallels — and they're worth very different amounts. Picking the exact version makes sure the market value you see is for the card you're actually looking at.

Paste an eBay sports-card or Pokémon listing link into FlipCheck. It works out which card it is and shows the card's market value, a grade ladder (what the card is worth raw and at each grade), a verdict on the asking price, and an offer helper that suggests what to offer.

FlipScore™ is FlipCheck's score for a listing. It weighs the asking price against the market value, how sure we are of that value, whether the listing can actually be bought, and how sure we are that we've identified the right card. Higher is better. It's a guide to help you decide, not a promise of profit.

FlipCheck prices single sports cards and single English Pokémon cards. Lots and bundles, sealed product (boxes and packs), reprints and custom cards, and Japanese Pokémon cards aren’t priced yet — FlipCheck tells you so instead of guessing.

Yes. FlipFoundry prices English Pokémon single cards the same way it prices sports cards, from a price guide. Japanese and other non-English Pokémon cards aren’t priced yet.

No. Values are estimates from a price guide and are for research purposes only. Market conditions change, and resale values vary. Always check the listing yourself — photos, condition, grade, and seller — before you buy.

No. FlipFoundry isn't a marketplace and doesn't give financial advice. Every purchase happens on eBay, between you and the seller.

Yes. If you can search for a card or copy a link from eBay, you can use FlipFoundry. Every eBay link opens the real listing, so you can check it yourself before you buy.
