Worth grading — even a PSA 9 beats raw

A PSA 10 Roy Campanella #31 sells for $14,239 against $55.51 raw: a $14,183 spread, 257× the ungraded price. Even a PSA 9 ($2,397) 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.
