Worth grading — even a PSA 9 beats raw
A CGC 10 Gastrodon West Sea sells for $130 against $10.93 raw: a $119 spread, 12× the ungraded price. Even a PSA 9 ($46.35) 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.
