Is Spider-Man [Preliminary Art] #29 worth grading?
Marvel · Marvel 2020 Masterpieces · full price guide →
Worth grading — even a PSA 9 beats raw
A Grade 9.5 Spider-Man [Preliminary Art] #29 sells for $88.00 against $13.79 raw: a $74.21 spread, 6.4× the ungraded price. Even a PSA 9 ($80.00) 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.
