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 30% — you'll need a very clean copy to hit PSA 10. PSA 10 profit of $8.47 is thin — grading fees and selling costs eat most of the margin.
