<p>[QUOTE=&quot;desertgem, post: 3712862, member: 15199&quot;]I think it is a misconception that the tolerances on a zinc lincoln cent is .010 gram&nbsp; &nbsp; &nbsp;&nbsp; ( someone years ago figured it was a percentage figure and just multiplied). but it is a Legal tolerance and that hasn&#039;t been changed unless someone has real info. Here is the law in 1988 on Cornell&#039;s Law site. I have continued using 0.13+/- and if It has been changed, I would appreciate it. Even some coin verification sites have it as 2.5+/-0.10. No Biggie, but I want to be accurate, Jim</p><p><br /></p><p><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>
