Negative expected value ($-7.52) — while a PSA 10 would be profitable, the probability-weighted outcome across all grades means you lose money on average at this grading tier. Only 89 sales per year — it may take time to find a buyer at full price. PSA 10 profit of $1.99 is thin — grading fees and selling costs eat most of the margin.
