Grading rarely pays for this card
Grade 9.5 copies of John Valentin #508 sell for $4.00, only $0.00 above the $19.99 raw price — less than an economy-tier grading fee. A PSA 9 ($3.26) sells for less than raw, so anything short of a 10 loses money. Keep it raw unless you are grading for the slab itself.
