Worth grading — even a PSA 9 beats raw
A PSA 10 M Mawile-EX sells for $1,750 against $30.65 raw: a $1,719 spread, 57× the ungraded price. Even a PSA 9 ($112) 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.
