Negative expected value ($-5.98) — while a PSA 10 would be profitable, the probability-weighted outcome across all grades means you lose money on average at this grading tier. The gem rate is only 18% — you'll need a very clean copy to hit PSA 10. Only 71 sales per year — it may take time to find a buyer at full price. PSA 10 profit of $14.23 is thin — grading fees and selling costs eat most of the margin.
