Worth grading — even a PSA 9 beats raw

A PSA 10 Slowbro sells for $55.00 against $0.21 raw: a $54.79 spread, 262× the ungraded price. Even a PSA 9 ($75.00) 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.
