Card Comps Overlay

Overlays recent eBay sold comps (raw vs PSA 10) on sports card listings so you can spot under- and over-priced cards at a glance.

Open any eBay sports card listing and Card Comps Overlay tells you what the card actually sells for. It reads the listing, finds recent sold listings for that exact card, and gives you one call: BUY, FAIR PRICE, or PASS — plus the fair value in dollars. What you see on every listing: • Recent sold prices split by condition — raw, PSA 9, and PSA 10 — each with the median, the price range, and the latest sales with dates. Every sale links to the real listing so you can check it yourself. • Whether it's worth grading. On a raw card, it shows what a PSA 9 or PSA 10 outcome sells for and what you'd net over the asking price. • Exact matches only. A comp has to match the year, player, card number, and parallel. When a card barely trades, it says "only 2 exact comps" instead of padding the average with a different card.
