Worth grading — even a PSA 9 beats raw
A PSA 10 Gastrodon East Sea sells for $500 against $13.73 raw: a $486 spread, 36× the ungraded price. Even a PSA 9 ($117) 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.
