Judging from the pics, I would venture a MS grade, but the level would need clearer photos. Like infinite said, it seems a little fuzzy. It's almost as if you're actually trying to get too close to the coin, and losing some focus ability. If this is true, you may find that you will get better pics by moving your camera farther away, and cropping and resizing. Photo editing software will be able to bring it closer for us without losing as much detail as a bad focus. You will definitely need a tripod, and also a timer setting on the camera to avoid all vibration.
My suggestion, unless it's what you're already doing:
1. Tripod
2. Timer setting
3. Put coin at least 8 inches away and only zoom closer to the level the camera can still focus on it's own and be happy. Usually not very much zoom.
Bottom line, I think folks usually try to get really close to a coin for good pictures, and they are actually sacrificing the capabilities of their camera at that point.
