Worth grading — even a PSA 9 beats raw
A PSA 10 Spider-Man [Diamond Preview] #29 sells for $1,950 against $13.00 raw: a $1,937 spread, 150× the ungraded price. Even a PSA 9 ($250) 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.
