Grading rarely pays for this card

Grade 9.5 copies of Cooper Flagg [Black Autograph Refractor] #28 sell for $3,300, only $0.00 above the $4,000 raw price — less than an economy-tier grading fee. A PSA 9 ($3,000) sells for less than raw, so anything short of a 10 loses money. Keep it raw unless you are grading for the slab itself.
