Is it worth grading?
Worth grading — even a PSA 9 beats raw
A PSA 10 Koga's Grimer sells for $133 against $4.03 raw: a $129 spread, 33× the ungraded price. Even a PSA 9 ($36.38) 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.
