Worth grading — even a PSA 9 beats raw

A PSA 10 M Blastoise-EX sells for $267 against $31.26 raw: a $236 spread, 8.5× the ungraded price. Even a PSA 9 ($98.85) 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.
