Worth grading — even a PSA 9 beats raw

A Grade 9.5 Michael Jordan [Black Diamond Sample] #23 sells for $110 against $5.50 raw: a $105 spread, 20× the ungraded price. Even a PSA 9 ($100) 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.
