Negative expected value ($-3.45) — 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 39 graded cards may be unreliable, and the market for this card in graded form may be illiquid.
