Worth grading — even a PSA 9 beats raw

A Grade 9.5 Patrick Ewing [Luminous] #T8B sells for $78.00 against $18.95 raw: a $59.05 spread, 4.1× the ungraded price. Even a PSA 9 ($70.81) 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.
