Worth grading — even a PSA 9 beats raw

A PSA 10 Mariano Rivera #302 sells for $680 against $59.36 raw: a $621 spread, 11× the ungraded price. Even a PSA 9 ($120) 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.
