Worth grading — even a PSA 9 beats raw
A PSA 10 Mike Caldwell #347 sells for $260 against $1.44 raw: a $258 spread, 180× the ungraded price. Even a PSA 9 ($40.89) 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.
