Worth grading — even a PSA 9 beats raw

A PSA 10 Dave Parker #29 sells for $1,816 against $4.00 raw: a $1,812 spread, 454× the ungraded price. Even a PSA 9 ($468) 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.
