Worth grading — even a PSA 9 beats raw
A Grade 9.5 Michael Jordan [Double] #6 sells for $157 against $71.82 raw: a $85.18 spread, 2.2× the ungraded price. Even a PSA 9 ($143) 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.
