Worth grading — even a PSA 9 beats raw

A PSA 10 Brock sells for $4,298 against $88.74 raw: a $4,209 spread, 48× the ungraded price. Even a PSA 9 ($234) 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.
