Worth grading — even a PSA 9 beats raw

A PSA 10 Seong-Jun Kim #CPA-SK sells for $629 against $131 raw: a $498 spread, 4.8× the ungraded price. Even a PSA 9 ($217) 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.
