Worth grading — even a PSA 9 beats raw
A Grade 9.5 John Mayberry #118 sells for $62.00 against $2.11 raw: a $59.89 spread, 29× the ungraded price. Even a PSA 9 ($56.67) 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.
