Grading rarely pays for this card

PSA 10 copies of サンダー sell for $1,600, only $0.00 above the $30,000 raw price — less than an economy-tier grading fee. A PSA 9 ($215) sells for less than raw, so anything short of a 10 loses money. Keep it raw unless you are grading for the slab itself.

Which grading company is best for サンダー?
