Worth grading — even a PSA 9 beats raw

A PSA 10 Ken Griffey #420 sells for $110 against $1.99 raw: a $108 spread, 55× the ungraded price. Even a PSA 9 ($38.50) 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.
