Worth grading — even a PSA 9 beats raw
A PSA 10 Grimer sells for $135 against $0.34 raw: a $135 spread, 397× the ungraded price. Even a PSA 9 ($30.07) 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.
