Worth grading — even a PSA 9 beats raw

A PSA 8 M Diancie-EX sells for $59.90 against $30.28 raw: a $29.62 spread, 2.0× the ungraded price. Even a PSA 9 ($57.84) 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.
