You lost money the last time a card came back a 9.

You enter recent sold prices (one tap opens them) and your grade odds — the sheet does every calculation after that.

Grading fees don’t care about hype. A $25 submission on a card that only clears at PSA 10 is a coin flip you’re paying to lose. Grade or Skip runs the math BEFORE you ship: enter sold comps for PSA 8/9/10 and your honest grade odds, and it fires a verdict — GRADE (green), BORDERLINE (amber), SKIP (red) — using expected value net of grading cost, shipping share, and selling fees.
