Grading rarely pays for this card

Grade 9 copies of Trea Turner #309 sell for $1.29, only $0.00 above the $3.90 raw price — less than an economy-tier grading fee. A PSA 9 ($1.29) sells for less than raw, so anything short of a 10 loses money. Keep it raw unless you are grading for the slab itself.
