Worth grading — even a PSA 9 beats raw

A PSA 10 Tim Duncan #4DG sells for $1,293 against $474 raw: a $819 spread, 2.7× the ungraded price. Even a PSA 9 ($1,250) 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.
