Worth grading — even a PSA 9 beats raw
A PSA 9 Dialga sells for $980 against $53.28 raw: a $927 spread, 18× the ungraded price. Even a PSA 9 ($980) 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.
