I recently found a standard size penny showing the tails side. On the other side, it is hollow, having a silver lining. The edges are beveled, as a standard penny, the color and weight seems to be the same. However, I can't tell if a portion of the penny has "slipped out", or if this is some kind of fake. (if the penny were to be laying flat on the tails side, it could hold a couple drops of water in it.) I could email a photo, but can't seem to attach to this site.
