Worth grading — even a PSA 9 beats raw

A PSA 10 John Marcum #69 sells for $6,715 against $17.17 raw: a $6,698 spread, 391× the ungraded price. Even a PSA 9 ($1,246) 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.
