Worth grading — even a PSA 9 beats raw

A PSA 10 Marshtomp sells for $652 against $85.14 raw: a $566 spread, 7.7× the ungraded price. Even a PSA 9 ($212) 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.
