Worth grading — even a PSA 9 beats raw
A PSA 10 Seong-Jun Kim #BSPA-SK sells for $460 against $209 raw: a $251 spread, 2.2× the ungraded price. Even a PSA 9 ($317) 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.
