Worth grading — even a PSA 9 beats raw

A PSA 10 Slowking sells for $379 against $2.04 raw: a $377 spread, 186× the ungraded price. Even a PSA 9 ($54.17) 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.
