Is Dikembe Mutombo [Refractor] #100 worth grading?

Worth grading — even a PSA 9 beats raw

A Grade 9.5 Dikembe Mutombo [Refractor] #100 sells for $36.00 against $6.35 raw: a $29.65 spread, 5.7× the ungraded price. Even a PSA 9 ($32.41) 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.
