Worth grading — even a PSA 9 beats raw
A PSA 10 Art Mahaffey #550 sells for $2,217 against $12.50 raw: a $2,205 spread, 177× the ungraded price. Even a PSA 9 ($323) 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.
