Worth grading — even a PSA 9 beats raw

A PSA 10 Armored Mewtwo sells for $9,558 against $295 raw: a $9,264 spread, 32× the ungraded price. Even a PSA 9 ($715) 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.
