About Ripbin
Ripbin is a free price guide, scanner, and marketplace for sports cards and trading-card games. We help collectors answer one question fast: what is this card actually worth?
How we price cards
Every value on Ripbin is built from real market activity, not guesswork. We combine two independent signals:
- Recent sales data — aggregated sold prices from SportsCardsPro, broken out by grade so you see ungraded value alongside PSA, BGS, SGC, and CGC gem-mint prices.
- Live eBay listings — current asking prices and active inventory pulled from the eBay Browse API, so you can cross-check a value against what cards are listed for right now.
Grade-by-grade methodology
A card's value is inseparable from its condition. Each card page shows an ungraded estimate plus values across the grading scale (PSA 7–10, BGS 9.5/10, SGC 10, CGC 10) when sales data exists. The headline number is always the ungraded estimate; graded values are labeled explicitly so nothing is conflated.
How often prices update
Card values move with the market. We refresh pricing on a rolling daily cadence, and every card page shows a “Prices updated” date so you always know how current a number is.
Who's behind Ripbin Research
Our guides and value rankings are produced by Ripbin Research — the in-house team that maintains the catalog, validates pricing sources, and writes the editorial “most valuable” and rookie-card guides. Every ranking is generated from our own catalog data, so the numbers, images, and ordering on a guide are specific to that page, not boilerplate.
Affiliate disclosure
Ripbin participates in the eBay Partner Network. When you buy a card after clicking an eBay link on our site, we may earn a commission — at no extra cost to you. This never changes the values we show; pricing is derived from sales data independently of any affiliate relationship. Read the full disclosure.
Where to go next
This page is the summary. The detail lives on its own pages, and each one is more specific than what is above.
- Pricing methodology — which source produced which number, why eBay-derived values are asking prices rather than sold prices, how often each pass runs, and where the method is weakest.
- Editorial policy — which pages are generated from data, which are drafted by AI and auto-published, and how the monthly investing picks are made.
- Contact — postal address, help@ripbin.com, and the form for reporting a price that looks wrong.
