Know what a
sports card
is worth
before you buy.
Search a card to see live eBay listings next to a market value from a price guide. Or paste an eBay sports-card or Pokémon listing into FlipCheck for the card's value, its value at each grade, a verdict and a suggested offer. Single cards only — lots, sealed product and Japanese Pokémon cards aren’t priced yet. Free to use.
Two tools. Both free.
Look up a card, or check a listing you've already found. Either way, you see a market value next to the asking price.
Listings
Search a player or a specific card and see live eBay listings next to a market value from a third-party price guide. If your search matches more than one version of the card, pick the exact one you mean.
FlipCheck
Paste an eBay sports-card or Pokémon listing link. FlipCheck shows the card's value, what it's worth at each grade, a verdict on the asking price and a suggested offer. Single cards only — lots, sealed product and Japanese Pokémon cards aren’t priced yet.
Search or paste
Type a card into Listings, or paste an eBay listing link into FlipCheck.
See the value
A market value from a price guide, for the same card, grader, and grade.
Check before you buy
Compare the value to the asking price, then look over the listing yourself.
A value you
can check.
FlipFoundry doesn't just show listings.
It shows what the card is worth — raw and graded.
Market value from a price guide
For the same card, grader, and grade — not what sellers are asking.
The exact version
Base, refractor, or numbered parallel: pick the one you mean so the value matches the card.
Value by grade
FlipCheck shows what the card is worth raw and at each grade.
A verdict and an offer helper
FlipCheck compares the asking price to the value and suggests what to offer.
Built to be honest
Clear about what it knows — and about what it doesn't.
No made-up numbers
When we don’t have a value for a card, we say so instead of guessing.
NO GUESSESValues are estimates
Every value comes from a price guide. It’s an estimate, not a promise of what a card will sell for.
ESTIMATESYou make the call
FlipFoundry doesn’t buy or sell cards. Every eBay link opens the real listing, so you can check it yourself.

FlipFoundry is a research tool. Values are estimates from a price guide and are not guarantees of future results. Always check the listing yourself before you buy.
