Worth grading — even a PSA 9 beats raw
A PSA 10 Ken Chase #59 sells for $3,681 against $10.45 raw: a $3,671 spread, 352× the ungraded price. Even a PSA 9 ($554) 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.
