Negative expected value ($-8.78) — 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 27 graded cards may be unreliable, and the market for this card in graded form may be illiquid. The gem rate is only 11% — you'll need a very clean copy to hit PSA 10. Only 18 sales per year — it may take time to find a buyer at full price. PSA 10 profit of $3.70 is thin — grading fees and selling costs eat most of the margin.

Check the downside before you buy

Compare the lower-grade reference prices below with your buy price, grading cost and selling fees. Shipping and tax reduce the result further. Missing prices do not establish a resale floor; a population gem rate is not your card's personal probability.
