Worth grading — even a PSA 9 beats raw

A PSA 10 Slowpoke & Psyduck-GX sells for $2,470 against $307 raw: a $2,163 spread, 8.1× the ungraded price. Even a PSA 9 ($509) 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.
