Worth grading — even a PSA 9 beats raw

A PSA 10 Steve Carlton #300 sells for $5,600 against $4.18 raw: a $5,596 spread, 1340× the ungraded price. Even a PSA 9 ($387) 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.
