Worth grading — even a PSA 9 beats raw
A PSA 10 Jim Konstanty #27 sells for $2,154 against $7.09 raw: a $2,147 spread, 304× the ungraded price. Even a PSA 9 ($327) 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.
