Worth grading — even a PSA 9 beats raw
A PSA 10 Buster Posey #91A-BP sells for $597 against $130 raw: a $467 spread, 4.6× the ungraded price. Even a PSA 9 ($211) 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.
