Should You Grade?
Negative expected value ($-1.55) — while a PSA 10 would be profitable, the probability-weighted outcome across all grades means you lose money on average at this grading tier. Low grading population — gem rates based on only 70 graded cards may be unreliable, and the market for this card in graded form may be illiquid. The gem rate is only 17% — you'll need a very clean copy to hit PSA 10. Only 91 sales per year — it may take time to find a buyer at full price. PSA 10 profit of $13.86 is thin — grading fees and selling costs eat most of the margin.
