Is Jerry Koosman #90 worth grading?

Worth grading — even a PSA 9 beats raw

A Grade 9.5 Jerry Koosman #90 sells for $660 against $5.31 raw: a $655 spread, 124× 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.

Raw (NM): $5.31
