Worth grading — even a PSA 9 beats raw

A PSA 10 Giovanni's Nidoqueen sells for $196 against $31.46 raw: a $164 spread, 6.2× the ungraded price. Even a PSA 9 ($83.29) 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.
