Worth grading — even a PSA 9 beats raw

A Grade 9.5 Tim Duncan sells for $692 against $183 raw: a $510 spread, 3.8× the ungraded price. Even a PSA 9 ($500) 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.
