Built for one decision: grade it or don't.

Three things that make that decision objective instead of a gut call.

Stop losing money on bad grades.

Each PSA submission costs $25–$100. Submit one wrong card and your profit is gone. SlabScore's 0–100 score tells you whether the card clears its own fee before you pay.

Compare every major grader.

TAG Bulk is $19. PSA Value is $32.99. CGC Modern is $30. Same card, different economics. SlabScore surfaces the cheapest grader for each card's value tier — PSA, CGC, TAG, BGS, or ACE.

Track a portfolio, not a spreadsheet.

Import 500 cards via CSV, score them all, sort by profit potential. Live price refreshes. The Chrome extension scores cards while you shop eBay and TCGPlayer.

What you can actually do.

Four features that go beyond a basic ROI calculator.
