Worth grading — even a PSA 9 beats raw

A PSA 10 Poliwhirl sells for $74.56 against $24.52 raw: a $50.04 spread, 3.0× the ungraded price. Even a PSA 9 ($81.76) 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.
