Worth grading — even a PSA 9 beats raw

A PSA 10 Phil Niekro #503 sells for $856 against $7.33 raw: a $849 spread, 117× the ungraded price. Even a PSA 9 ($136) 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.
