Is Spider-Man [What If] #29 worth grading?

Marvel · Marvel 2020 Masterpieces · full price guide →

Worth grading — even a PSA 9 beats raw

A CGC 10 Spider-Man [What If] #29 sells for $44.63 against $8.37 raw: a $36.26 spread, 5.3× the ungraded price. Even a PSA 9 ($38.77) 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.
