Worth grading — even a PSA 9 beats raw
A Grade 9.5 Dikembe Mutombo [Refractor, w/Coating] #R14 sells for $88.00 against $15.94 raw: a $72.06 spread, 5.5× the ungraded price. Even a PSA 9 ($79.99) 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.
