Worth grading — even a PSA 9 beats raw
A PSA 10 Kon Knueppel [Gold Refractor] #TAUR2-KK sells for $5,600 against $1,238 raw: a $4,363 spread, 4.5× the ungraded price. Even a PSA 9 ($3,075) 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.
