I did something similar but a lot cruder. My good camera with the macro lens died. I tried using a point & shoot but my hand wasn't steady enough to satisfy me. I placed the coin at the bottom of a tall drinking glass next to a desk light and laid the camera on top of the glass. It could have been better if I'd played with the lighting, but it made a good enough tripod to get a post-able image. Now I know what country the coins are from.
