<p>[QUOTE=&quot;Conder101, post: 300139, member: 66&quot;]Except the mints allowed tolerance for the zinc cent is +/- .1 grams.&nbsp; So a normal cent can weigh anywhere between 2.4 and 2.6 grams&nbsp; I worked out the weight of the copper plating one time&nbsp; and it is .05 grams.&nbsp; An added zinc plating would be about .03 grams.&nbsp; So if you have&nbsp; typical zinc cent you could strip off the plating, or add an extra zinc plating and it would not be definitely detectable by weight.</p><p><br /></p><p>A coating of Mercury just might be detectable, but it would have to at least four times thicker than the copper plating is to be absolutely sure. and if it is that thick I&#039;m sure you would be able to visibly tell it was there.&nbsp; A mercury coating as thick as the copper plating is weighs .06 grams.&nbsp; (And the copper plating is actually considered to be rather thick.&nbsp; It is very easy to put a thinner layer on and still achieve the color you are shooting for.&nbsp; And the weight change will be even less.)</p><p><br /></p><p>So, since you can&#039;t know what the original starting weight of the coin actually was, weighing it really won&#039;t tell you much.&nbsp; (Unless it started out at the heavy end of the tolerance range, after the plating or coating it will still be within the tolerance range.[/QUOTE]</p><p><br /></p>
