Worth grading — even a PSA 9 beats raw

A Grade 9.5 Mike Corrigan #236 sells for $30.00 against $1.05 raw: a $28.95 spread, 29× the ungraded price. Even a PSA 9 ($27.55) 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.
