FlipScore™ evaluates active listings using sold comps, Active Ask, estimated fees, shipping, and condition/grade fit to estimate real net ROI.
A deal-quality score that estimates real net ROI — using sold comps, active ask, fees, and grade fit.
Derived from verified eBay sold prices for the same card, grader, and grade — not sticker prices or list prices. This is what the card actually sells for.
A reference price from SportsCardsPro — shown alongside Market Value for context. Guide values are estimates, not guaranteed market prices.
Verified eBay sold prices for exact card, grader, and grade matches — the primary FlipScore™ input.
The lowest verified Buy-It-Now listing for the card right now — what you can actually buy it for today.
Estimated profit after eBay fees, payment processing, and shipping — the number that matters.

FlipScore™ is FlipFoundry's deal-quality score. It evaluates each active listing using sold comps (verified eBay sales), Best Active Ask, estimated eBay fees, shipping, and condition/grade fit. The result is an estimated net ROI — the amount you'd pocket after a realistic resale. Higher FlipScores indicate stronger deals backed by more comp evidence.
Market Value is derived from recent verified eBay sold prices for the same card, grader, and grade. Guide Value is a reference price from SportsCardsPro — a third-party price guide. Guide values are estimates, not market prices. When available, FlipScore™ uses Market Value (sold comps) as the primary signal; Guide Value is shown as a secondary reference.
When you search a card, FlipFoundry queries eBay for active Buy-It-Now listings and recent sold comps. It clusters exact matches (same player/character, grader, grade) and runs the FlipScore™ algorithm — comparing the best active ask against the sold median, factoring in fees and shipping, and surfacing an estimated net ROI with a confidence rating.
No. All estimates are based on historical eBay sold data and are for research purposes only. Market conditions change, and actual sale prices vary. FlipFoundry helps you identify better-than-average buying opportunities, but past performance does not guarantee future results. Always do your own due diligence before buying.
Yes. FlipFoundry scans both sports cards (PSA, BGS, CGC, SGC) and Pokémon (PSA, BGS, CGC). Pokémon raw support is available in beta with condition and data-confidence safeguards — thin-data listings may show Research or No Data while graded slabs across both verticals are fully supported.
Each signal is scored using exact comp matching against verified recent sales for the same card condition. The algorithm factors in edge % vs the 30-day sold median, comp count, and freshness weighting — so higher scores mean stronger, more recent evidence.
eBay is the primary marketplace today. Raw and graded cards across sports and Pokémon are supported. Additional platforms are on the roadmap.
Cards are revalidated continuously — approximately every 60 seconds. Stale or changed listings are flagged and re-scored automatically.
The signal is automatically invalidated and removed from your feed. No manual cleanup required — dead signals disappear on their own.
Yes. All plans are self-serve with no lock-in. You can upgrade, downgrade, or cancel from your account at any time.
No credit card required. Setup takes 30 seconds.
FlipFoundry is a research tool. All profit estimates are based on historical eBay sold data and are not guarantees of future results.
