Worth grading — even a PSA 9 beats raw

A PSA 10 Nidoking sells for $54.82 against $15.59 raw: a $39.23 spread, 3.5× the ungraded price. Even a PSA 9 ($52.40) 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.
