[QUOTE="Collect89, post: 1155560, member: 15445"]I'll get you some information when I have more time. For right now, here are a couple bits of data for you: There is a reason that most coins in the World are round. They are easier to manufacture. You can make a round hole for the coin to fit into quite easily. It is far more difficult to drill a multi-sided hole. Look into the compositions used by the USA and other countries.
