Grading rarely pays for this card

PSA 10 copies of Grass Energy sell for $11.00, only $10.55 above the $0.45 raw price — less than an economy-tier grading fee. Even a PSA 9 ($31.78) clears the raw price after an economy-tier ~$25 fee, so a near-miss still comes out ahead. Keep it raw unless you are grading for the slab itself.
