Worth grading — even a PSA 9 beats raw

A PSA 10 Jack Wilson #31 sells for $4,913 against $14.50 raw: a $4,898 spread, 339× the ungraded price. Even a PSA 9 ($737) 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.
