Grading rarely pays for this card

Grade 9.5 copies of Kobbie Mainoo [Purple Wave Refractor] #78 sell for $53.00, only $0.00 above the $94.28 raw price — less than an economy-tier grading fee. A PSA 9 ($48.00) sells for less than raw, so anything short of a 10 loses money. Keep it raw unless you are grading for the slab itself.
