Worth grading — even a PSA 9 beats raw

A PSA 10 Nidoking sells for $135 against $0.79 raw: a $134 spread, 171× the ungraded price. Even a PSA 9 ($45.82) clears the raw price after an economy-tier ~$25 fee, so a near-miss still comes out ahead. Centering is the usual reason a clean copy misses the 10 — measure it before you submit.
