Worth grading — even a PSA 9 beats raw

A PSA 10 Gyarados sells for $4,992 against $58.57 raw: a $4,934 spread, 85× the ungraded price. Even a PSA 9 ($168) 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.
