Worth grading — even a PSA 9 beats raw

A PSA 10 Tom Seaver sells for $185 against $7.84 raw: a $177 spread, 24× the ungraded price. Even a PSA 9 ($67.45) 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.
