Worth grading — even a PSA 9 beats raw

A PSA 9 Slowbro sells for $99.00 against $1.92 raw: a $97.08 spread, 52× the ungraded price. Even a PSA 9 ($99.00) 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.
