Is Spider-Man #MM1 worth grading?

Marvel · Marvel 2017 Spider-Man Metals · full price guide →

Worth grading — even a PSA 9 beats raw

A Grade 9.5 Spider-Man #MM1 sells for $176 against $40.79 raw: a $135 spread, 4.3× the ungraded price. Even a PSA 9 ($160) 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.
