I found this info on the U.S. Mint web site and thought it was pretty interesting. If you've never seen how this is done it is well worth watching. Go to..."How coins are made - Virtual Tour" sit back, relax and soak in the information, its a great video, except for constantly calling the cent a "penny". http://www.usmint.gov/about_the_mint/index.cfm?flash=yes&action=coin_production
