Worth grading — even a PSA 9 beats raw

A PSA 10 Slowking sells for $27,000 against $253 raw: a $26,747 spread, 107× the ungraded price. Even a PSA 9 ($1,357) 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.
