Worth grading — even a PSA 9 beats raw
A PSA 10 Jim Kaat #715 sells for $483 against $1.94 raw: a $481 spread, 249× the ungraded price. Even a PSA 9 ($56.00) 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.
