Worth grading — even a PSA 9 beats raw

A PSA 10 George Brett #100 sells for $10,830 against $2.45 raw: a $10,828 spread, 4420× 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.
