Worth grading — even a PSA 9 beats raw

A PSA 10 Cliff Mapes #13 sells for $1,479 against $6.33 raw: a $1,472 spread, 234× the ungraded price. Even a PSA 9 ($564) 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.
