Worth grading — even a PSA 9 beats raw
A PSA 10 Slowbro sells for $1,275 against $45.01 raw: a $1,230 spread, 28× the ungraded price. Even a PSA 9 ($174) 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.
