Worth grading — even a PSA 9 beats raw
A PSA 10 Ken Brett #157 sells for $425 against $1.39 raw: a $424 spread, 306× the ungraded price. Even a PSA 9 ($158) 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.
