Interesting video called The Value of Silver, produced by Endeavour Silver. It explains why silver is used as money, both historically and today. http://www.youtube.com/watch?v=fK6aQ_T6jTE Full disclosure: I am the producer of the video, and we produced it on behalf of Endeavour Silver. Aside from that, Endeavour is not involved; all of the interviews we did were with independent figures, and nobody received money for being in the video. It is intended for education and enlightenment. Enjoy. Devon Cooke Storybubble Media
