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.
