<p>[QUOTE=&quot;cladking, post: 949014, member: 68&quot;]It&#039;s not that silver and clad have the exact same electrical signatures just that they are very similar. </p><p>Even the coin discriminators used in vending machines of the 1960&#039;s could have been set to exclude clad but in doingf so they would have excluded lots of the silver coins as well.&nbsp; This made the composite metals very dangeroues to the vending industry.&nbsp; In the hearings to determine a substitute for silver the heads of the American Automatic Vending Association said that anything other than a clad sort of composition would be acceptable.&nbsp; Ironically this might have been the stimulus that resulted in the copper nickel clad copper coinage.&nbsp; </p><p><br /></p><p>Up until the early-&#039;70&#039;s both silver and clad worked in most vending machines but when silver became so scarce the discriminators were adjusted to reject anything but clad of the proper size and weight.&nbsp; Very few machines now days accept silver.[/QUOTE]</p><p><br /></p>
