Worth grading — even a PSA 9 beats raw
A PSA 10 Onix sells for $523 against $53.07 raw: a $470 spread, 9.9× the ungraded price. Even a PSA 9 ($125) 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.
