Worth grading — even a PSA 9 beats raw

A PSA 10 Groudon ex sells for $80,790 against $251 raw: a $80,539 spread, 322× the ungraded price. Even a PSA 9 ($8,204) 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.
