You do have an issue with a lot of glare on your images. By block the light with a curtain of even plastic grocery bag platic, it will reduce the glare. You can make a curtain with a wire hanger bent a bit.

After this hanger is bent, you can put a plastic grocery bag (or two if light is too strong) onto the hanger. Place the curtain between the light source and the coin to remove the glare. Often when most take images of what they would like to show, they put the light pointing in that direction. The problem is that the glare turns that area all white. Preventing us from seeing what you see. So using this curtain you make, then it will remove the glare, but allow some light through. Also if you allow the light to fall across the area in question, rather than directly on that area, it can be seen easier. A single light source is best for micro photos. This creates light and shadows. With two lights, it creates false shadows on the devices. Even an unwanted light from a window or room light can be an issue. But with a facial tissue or something to block the light from the coin, this can be prevented from happening on your images.
But I spotted the trails on the NW side of the tops on LIBERTY.
