Worth grading — even a PSA 9 beats raw

A PSA 10 Slowpoke & Psyduck-GX sells for $2,284 against $347 raw: a $1,937 spread, 6.6× the ungraded price. Even a PSA 9 ($555) 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.
