Worth grading — even a PSA 9 beats raw
A PSA 10 Coalossal sells for $185 against $4.21 raw: a $181 spread, 44× the ungraded price. Even a PSA 9 ($51.70) 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.
