Worth grading — even a PSA 9 beats raw
A PSA 10 Bob Boone #131 sells for $136 against $3.62 raw: a $132 spread, 37× the ungraded price. Even a PSA 9 ($66.60) 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.
