Worth grading — even a PSA 9 beats raw

A PSA 10 Ron Santo #670 sells for $2,632 against $18.63 raw: a $2,613 spread, 141× the ungraded price. Even a PSA 9 ($823) 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.
