Is it worth grading?

Grading pays off only if the chance of a 10 is high enough to cover the fee and the risk of a 9. Set your own numbers; the prices are filled in from this page.

Example inputs, not a prediction for this card. Everything below a 9 is valued at the ungraded price. Current PSA fees: psacard.com.
