Worth grading — even a PSA 9 beats raw
A PSA 10 Sam Chapman #52 sells for $6,085 against $24.25 raw: a $6,061 spread, 251× the ungraded price. Even a PSA 9 ($915) 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.
