Negative expected value ($-0.61) — 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 29% — you'll need a very clean copy to hit PSA 10. PSA 10 profit of $14.23 is thin — grading fees and selling costs eat most of the margin.
