Worth grading — even a PSA 9 beats raw
A PSA 10 Kon Knueppel [Flash Drop] #SS-29 sells for $460 against $68.67 raw: a $391 spread, 6.7× the ungraded price. Even a PSA 9 ($148) 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.
