Worth grading — even a PSA 9 beats raw

A PSA 10 Tommy John #520 sells for $861 against $3.18 raw: a $858 spread, 271× the ungraded price. Even a PSA 9 ($717) 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.
