Worth grading — even a PSA 9 beats raw
A PSA 10 Grumpig sells for $115 against $0.94 raw: a $114 spread, 123× the ungraded price. Even a PSA 9 ($95.26) 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.
