Worth grading — even a PSA 9 beats raw

A PSA 10 Kobe Bryant #91 sells for $834 against $158 raw: a $676 spread, 5.3× the ungraded price. Even a PSA 9 ($338) 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.
