Is Thor #66 worth grading?

Marvel · Marvel 1966 Super Heroes · full price guide →

Worth grading — even a PSA 9 beats raw

A Grade 9.5 Thor #66 sells for $2,613 against $24.15 raw: a $2,589 spread, 108× the ungraded price. Even a PSA 9 ($2,375) 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.
