Worth grading — even a PSA 9 beats raw

A PSA 10 Dirk Nowitzki #99 sells for $580 against $186 raw: a $394 spread, 3.1× the ungraded price. Even a PSA 9 ($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.
