<p>[QUOTE=&quot;desertgem, post: 3859144, member: 15199&quot;]Pete , I have seen the 0.100 gram tolerance mentioned before in various posts, but where is that found in the government publications?&nbsp; The tolerances I quoted above does not separate the zinc cent tolerance from the previous. I would appreciate the basis of the 0.100 grams. One other forum used a formula of .13X2.50/3.11=.10 ( rounded), but I can&#039;t find that in government tolerances below , which were last approved in1988 in this info.&nbsp; Thanks Jim</p><p><br /></p><p>Tolerances --&gt; <a href="https://www.law.cornell.edu/uscode/text/31/5113" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.law.cornell.edu/uscode/text/31/5113" rel="nofollow">https://www.law.cornell.edu/uscode/text/31/5113</a>[/QUOTE]</p><p><br /></p>
