Volcarona [Master Ball] #19

Negative expected value ($-0.28) — 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 66 graded cards may be unreliable, and the market for this card in graded form may be illiquid. Only 30 sales per year — it may take time to find a buyer at full price. PSA 10 profit of $10.81 is thin — grading fees and selling costs eat most of the margin.
