Wow that looked great!
Don't know anything about coin magic (yet) so I don't even know if this is what you have done, but at 0:37 it looks like there is two coins there? It looked a little odd the first time viewing - I didn't really see anything but just looked a bit off, so I watched it another 7-8 times to check it out. Overall though it looked really good.
Also just on the video, it would be better to have the music edited in instead of background sound as the quality is really average.
