Worth grading — even a PSA 9 beats raw

A PSA 10 Enos Slaughter #30 sells for $16,483 against $65.70 raw: a $16,418 spread, 251× the ungraded price. Even a PSA 9 ($499) 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.
