I'm going to address the photos rather than the coin. With just a little tweaking, I think you're going to be astonished at the quality of the shots you'll get - I can see the potential in your camera.
First, the burring on the first photo indicates that the camera moved when you snapped the shutter. Virtually all digital cameras have a delayed shutter - you should be able to set yours for a 2-second delay. Do so, step away from the camera, and your shots should come out a whale of a lot sharper.
Second, the second pic is in focus on the bottom half, and no so much on the top half. This is because the camera and the coin were not perfectly parallel - one was tilted by comparison to the other. Correct this, and you're in business.
Your lighting is adequate to show excellent details, but the white balance is a little off (towards the yellow end of the scale, typical with tungsten lighting). This might be able to be corrected at the camera, or is easily done in postprocessing. We can address this later, if you like.
