Low grading population — gem rates based on only 30 graded cards may be unreliable, and the market for this card in graded form may be illiquid. Only 26 sales per year — it may take time to find a buyer at full price. PSA 10 profit of $16.81 is thin — grading fees and selling costs eat most of the margin.
