Worth grading — even a PSA 9 beats raw

A PSA 10 Blastoise-EX sells for $325 against $16.17 raw: a $309 spread, 20× the ungraded price. Even a PSA 9 ($53.27) 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.
