Worth grading — even a PSA 9 beats raw
A PSA 10 Kon Knueppel [Gold Mojo] #80CR2-KK sells for $7,100 against $675 raw: a $6,425 spread, 11× the ungraded price. Even a PSA 9 ($995) 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.
