Worth grading — even a PSA 9 beats raw
A Grade 7 David Robinson [Luminescent] #T9B sells for $149 against $25.23 raw: a $124 spread, 5.9× the ungraded price. Even a PSA 9 ($72.59) 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.
