Worth grading — even a PSA 9 beats raw

A PSA 10 John Williamson #234 sells for $190 against $1.00 raw: a $189 spread, 190× the ungraded price. Even a PSA 9 ($100) 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.
