Worth grading — even a PSA 9 beats raw

A PSA 9 Nidoking sells for $860 against $3.92 raw: a $856 spread, 219× the ungraded price. Even a PSA 9 ($860) 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.
