Worth grading — even a PSA 9 beats raw
A PSA 10 Mark Koenig #39 sells for $7,853 against $23.50 raw: a $7,830 spread, 334× the ungraded price. Even a PSA 9 ($1,174) 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.
