Negative expected value ($-2.15) — 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 35 graded cards may be unreliable, and the market for this card in graded form may be illiquid. The gem rate is only 31% — you'll need a very clean copy to hit PSA 10.
