Is Moon Knight [Bronze] #MM21 worth grading?

Worth grading — even a PSA 9 beats raw
A Grade 9.5 Moon Knight [Bronze] #MM21 sells for $386 against $57.80 raw: a $328 spread, 6.7× the ungraded price. Even a PSA 9 ($351) 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.
