Worth grading — even a PSA 9 beats raw

A PSA 10 Slowbro sells for $178 against $2.93 raw: a $175 spread, 61× the ungraded price. Even a PSA 9 ($353) 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.
