Worth grading — even a PSA 9 beats raw
A PSA 10 Mickey Cochrane #9 sells for $55,561 against $142 raw: a $55,420 spread, 392× the ungraded price. Even a PSA 9 ($2,621) 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.
