The decision
Is Nidoking worth grading?
Yes — even a PSA 9 Nidoking beats keeping it raw.
A 10 nets +$18,567 over the raw price and a 9 nets +$2,938. The grade only decides how much you make, not whether you do — so the question is just whether the copy is clean enough to avoid an 8 or worse.

Fee uses PSA's value-tiered service levels ($300 for a card worth $19,537 graded); shipping and insurance are extra. Break-even assumes the copy comes back a 10 or a 9 — a lower grade is worse than either.
