<p>[QUOTE=&quot;desertgem, post: 2006584, member: 15199&quot;]I estimate that the latter coin would weigh 3.88 grams if that helps and the assumptions about volume is correct. But if the tolerances were +/-0.1 gram, the first could weigh 3.96 and a copy of the second variety 3.98 so they would theoretically be indistinguishable (&nbsp; over lapping) although there should be some color difference.[/QUOTE]</p><p><br /></p>
