Worth grading — even a PSA 9 beats raw
A PSA 10 George Brett #580 sells for $6,296 against $5.49 raw: a $6,290 spread, 1147× the ungraded price. Even a PSA 9 ($440) 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.
