Worth grading — even a PSA 9 beats raw

A Grade 9.5 Spider-Man [Preliminary Art] #29 sells for $87.00 against $13.79 raw: a $73.21 spread, 6.3× the ungraded price. Even a PSA 9 ($79.00) 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.
