<p>[QUOTE=&quot;ldhair, post: 2322163, member: 11540&quot;]Chris Pilliod gave a talk at the Fun show about this topic. His company made a new steel that the mint was testing for the cent and the nickel. There is a long list of stuff that has to be tested. By current law the material must be metallic.</p><p>The mint has a special room to do the striking test. They use Martha Washington dies for the test and keep track of every coin that is struck. The process takes months of work.</p><p>Vending is a really big issue. There are many machines that can&#039;t be changed over because of the cost. They would need to be replaced. Tough choices.[/QUOTE]</p><p><br /></p>
