Worth grading — even a PSA 9 beats raw
A PSA 10 Giovanni's Nidoking sells for $2,712 against $220 raw: a $2,492 spread, 12× the ungraded price. Even a PSA 9 ($476) 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.
