Worth grading — even a PSA 9 beats raw

A PSA 10 Ken Boyer #125 sells for $5,159 against $20.74 raw: a $5,138 spread, 249× the ungraded price. Even a PSA 9 ($5,124) 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.
