<p>[QUOTE=&quot;Sheila Ruley, post: 2431538, member: 76273&quot;]Agreed. Here is something I found on another link. To answer your question about tolerance ranges, the tolerance for the brass cents was .13 grams and for the copper plated zinc it was .1 grams So a brass 1983 cent could weigh anywhere from 2.97 grams to 3.23 grams. A copper plated zinc 1983 cent could weigh from 2.4 to 2.6 grams so there is no overlap at all between the two weight standards. Even an over weight zinc and an underweight brass would still be .4 grams apart in weight. So there would be no confusing the two.[/QUOTE]</p><p><br /></p>
