Product summary

Review the store description, core capabilities, and common use cases.

SlabScore analyzes trading cards on eBay, TCGPlayer, and PriceCharting to tell you whether a card is worth sending to a professional grading company. Visit any card listing and get an instant score from 0-100 that factors in profit potential, market depth, grade premium, and downside protection.

HOW IT WORKS

Browse cards on supported marketplaces and SlabScore automatically extracts the card name, price, and variant. The extension scores each card and displays a badge directly on the page with a clear recommendation: Strong Grade, Grade, Consider, or Skip.
