Worth grading — even a PSA 9 beats raw
A PSA 10 Marty Marion #40 sells for $5,467 against $19.95 raw: a $5,447 spread, 274× the ungraded price. Even a PSA 9 ($2,031) 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.
