Worth grading — even a PSA 9 beats raw
A Grade 9.5 Kevin Knox [Patch Autograph] #135 sells for $825 against $130 raw: a $695 spread, 6.3× the ungraded price. Even a PSA 9 ($198) 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.
