Hobby Card Index: Track, price, and flip sports & trading cards smarter

Hey Product Hunt! I'm Sean, the founder of Hobby Card Index. I built HCI because I was frustrated with the lack of real tools for card collectors. Most platforms give you a price lookup and call it a day. I wanted something that actually helps you make smarter decisions — whether that's knowing which raw cards are worth sending to PSA, finding underpriced listings before anyone else, or tracking how your collection's value moves week to week. A few things I'm most proud of: - The Grading ROI Engine analyzes 3,100+ cards to tell you exactly where the best grading opportunities are. Some cards have a 50x+ value multiplier from raw to graded. - The Workbench Deal Finder pulls live eBay listings priced below market value — right now there are 120+ deals live, with the best at 80% below market. - We track 18+ card categories — not just baseball. Pokemon, Dragon Ball, Soccer, Magic: The Gathering, One Piece, Wrestling, and more. - Market Analytics with forecasting, volume share, and sales velocity heat maps across every category. We're a small team and every feature was built because we needed it ourselves as collectors. Would love your feedback — and if you collect cards, come check out the Workbench. The deals refresh every few hours.

HobbyCardIndex is the tool I always wanted and could never find. Every card, every price, in one place.
Snap a card and get its real price in seconds. Track your whole collection and see what it's actually worth not what one loud listing wants you to think. Watch what's moving across the market, check whether a card is even worth grading before you send it in, and dig through 10 million cards.
