Worth grading — even a PSA 9 beats raw
A Grade 9.5 Kon Knueppel #80CR2-KK sells for $880 against $314 raw: a $566 spread, 2.8× the ungraded price. Even a PSA 9 ($800) 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.
