<p>[QUOTE="Conder101, post: 164839, member: 66"]You could possibly get away with that with the cents since no vending machines take cents anymore. But you would have some problems with the five cent. these coins would have to work interchangably with the current coins in vending machines. The coins are normally passed through a magnetic field and the electromagnetic properties of the coin would distort the field in known ways resulting in a specific signal. One other function of the field is to reject steel slugs. This would cause them to reject a copper clad steel coin. Another problem is that the new coin needs to be the same size and weight that the machine expects the nickel to be. A copper clad zinc or copper clad steel would be lighter than the current nickel and would be rejected. Or if they were reprogramed to recognize the new coin, the old nickels would be dumped to the coin return. Of course it would be possible to design and program a coin mechanism that would work with both, but it would mean that every vending machine in the country would have to have their coin mechanism replaced. Just wait for the screams over that one.[/QUOTE]</p><p><br /></p>
