Worth grading — even a PSA 9 beats raw

A PSA 10 Kevin Porter Jr. [Purple] #KPJ sells for $66.00 against $21.90 raw: a $44.10 spread, 3.0× the ungraded price. Even a PSA 9 ($55.00) 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.
