Worth grading — even a PSA 9 beats raw
A PSA 10 Jerry Koosman #90 sells for $15,000 against $5.94 raw: a $14,994 spread, 2525× the ungraded price. Even a PSA 9 ($600) 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.
