Worth grading — even a PSA 9 beats raw

A PSA 10 Jim Palmer #340 sells for $2,723 against $2.52 raw: a $2,721 spread, 1081× the ungraded price. Even a PSA 9 ($96.58) 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.
