Worth grading — even a PSA 9 beats raw
A PSA 10 Brooks Robinson #307 sells for $9,117 against $47.50 raw: a $9,070 spread, 192× the ungraded price. Even a PSA 9 ($1,373) 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.
