Worth grading — even a PSA 9 beats raw

A Grade 9.5 Doctor Doom [Silver Sparkle] #18 sells for $33.00 against $3.71 raw: a $29.29 spread, 8.9× the ungraded price. Even a PSA 9 ($29.97) 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.
