<p>[QUOTE=&quot;Conder101, post: 8024052, member: 66&quot;]Made out of what??&nbsp; The standard CuNi clad that they use for the dime quarter and half won&#039;t work.&nbsp; A CuNi clad nickel would still cost 7 1/2 cents to make.</p><p><br /></p><p>The problem is they want any new material to allow a &quot;seamless&quot; introduction into the existing coins so they can be handled by the same equipment and without extensive modification of existing vending coin mechanisms.&nbsp; So the new coins can&#039;t be larger, smaller, thicker, heavier or lighter, and need to have the same electromechanical properties.&nbsp; They also need to strike up well and resist wear.&nbsp; It can&#039;t be done.&nbsp; Most coinage metals are the heavier elements,&nbsp; The cheaper abundant metals tend to be much less dense so to get the weight the same they are larger or thicker.&nbsp; Alloying with a heavier metal to get the size and weight right tends to either be a more expensive alloy or a much more difficult alloy to make which increases the cost.&nbsp; So far their best solution has been to stick with CuNi and reduce the more expensive Ni content and increasing the Cu.&nbsp; it works because Cu and Ni have almost the same density so the weight and size don&#039;t change.&nbsp; That was how the got the 4.9 cent alloy.&nbsp; But both Cu and Ni have risen in price since then.[/QUOTE]</p><p><br /></p>
