Worth grading — even a PSA 9 beats raw

A PSA 10 Brock Purdy #21 sells for $654 against $148 raw: a $507 spread, 4.4× the ungraded price. Even a PSA 9 ($235) 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.
