Grading rarely pays for this card

Grade 9.5 copies of Leon Durham #330 sell for $88.00, only $4.00 above the $84.00 raw price — less than an economy-tier grading fee. A PSA 9 ($79.99) sells for less than raw, so anything short of a 10 loses money. Keep it raw unless you are grading for the slab itself.
