Worth grading — even a PSA 9 beats raw
A Grade 9.5 Black Cat [Blue] #MM6 sells for $446 against $285 raw: a $161 spread, 1.6× the ungraded price. Even a PSA 9 ($405) 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.
