Worth grading — even a PSA 9 beats raw

A PSA 10 Ken Brett #89 sells for $2,304 against $1.38 raw: a $2,303 spread, 1670× the ungraded price. Even a PSA 9 ($1,920) 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.
