Is it worth grading?
Grading rarely pays for this card
PSA 10 copies of Cooper Flagg / Kon Knueppel [Blue] #CFKK sell for $299, only $0.00 above the $309 raw price — less than an economy-tier grading fee. A PSA 9 ($249) sells for less than raw, so anything short of a 10 loses money. Keep it raw unless you are grading for the slab itself.
