Worth grading — even a PSA 9 beats raw
A PSA 10 Porygon sells for $329 against $17.64 raw: a $311 spread, 19× the ungraded price. Even a PSA 9 ($94.63) 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.
