By looking at the photo of your ebay example, I would expect the center of the reverse to be gold in color, the raised details on the coin to be frosty silver and the fields to be silver with a mirror finish. When you put a camera directly over a silver mirror finish often the mirror surface will reflect off the lens and will appear black in color in the photo. In the first photo of the reverse where the coin appears with a gold center and the details and fields silver in color, the camera is not directly over the coin, but shooting the image at an angle.
You are correct in your analysis that lighting and camera angle play a major role in getting quality photos that make the image appear as in hand.
