Worth grading — even a PSA 9 beats raw
A PSA 10 Tim Duncan #I1 sells for $266 against $2.50 raw: a $264 spread, 106× the ungraded price. Even a PSA 9 ($50.00) 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.
