I hadn't noticed that an Indian-head penny was used - that is pretty cool! It is possible that this machine only works with older coins. I know that my Hexaphone only works with the period nickels - they are noticably thinner than new nickels. I would like to see more footage too - wonder if the producer will post more if asked? Apparently the producer posted the video. Maybe a bunch of us could post (under "text comments") that we would like to see more footage and see what happens.
