Worth grading — even a PSA 9 beats raw

A Grade 9.5 Mariano Rivera [Refractor] #8 sells for $177 against $120 raw: a $57.00 spread, 1.5× the ungraded price. Even a PSA 9 ($161) 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.
