Worth grading — even a PSA 9 beats raw
A PSA 10 Brock Purdy [Black] #CB-31 sells for $428 against $182 raw: a $247 spread, 2.4× the ungraded price. Even a PSA 9 ($235) 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.
