Is it worth grading?
Worth grading — even a PSA 9 beats raw
A PSA 10 Billy Williams #350 sells for $674 against $5.16 raw: a $668 spread, 131× the ungraded price. Even a PSA 9 ($494) 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.
