SlabScore is a grading decision engine.

What it does

Paste or search a card and SlabScore pulls live market data and returns three things: a 0–100 score, a plain verdict — grade it, hold, or skip — and the cheapest grader and tier for that specific card. No spreadsheet, no cross-referencing five tabs.

The ones you decide to submit move through the whole journey with you — Watchlist → Raw → At Grader → Graded — so when a card comes back you can compare the grade you got to the grade you expected, and learn from it.

How the score works

The 0–100 score weighs four things at once:

• Profit after coststhe expected return once grading fees and shipping are subtracted — not the sticker gain.
• Market depthhow liquid the card actually is at each grade. A card that never trades is a risk, not a win.
• Grade premiumhow much more a high grade is worth than a low one. A flat premium means little upside for the gamble.
• Downsidewhat happens if it comes back lower than you hoped. The score respects the bad outcome, not just the dream one.

It's continuous, not a yes/no — a 72 and a 41 are genuinely different decisions, and the score moves the moment the market does.

Where the numbers come from

SlabScore reads live sold-comp data per grade and population reports — the same signals a serious collector checks by hand before pulling the trigger, pulled together and priced out in a few seconds instead of an afternoon. When the market shifts, the score shifts with it.

What SlabScore is not

• It doesn't buy, sell, or grade cards — it's the math you run before you decide.
• It isn't financial or investment advice. The score is a decision aid built on real data, but the market can move and grades are never guaranteed.
• It doesn't need your money to start. The core decision engine is free to use.

What it covers

SlabScore scores submissions across PSA, TAG, CGC, BGS, and ACE, and works with Pokémon, Magic: The Gathering, Yu-Gi-Oh!, and sports cards — with the fees, turnaround, and per-grader market baked into every score.
