<p>[QUOTE=&quot;Malleus Maleficarum, post: 4608672, member: 113425&quot;]I was thinking of buying a Sigma Metalytics PMV.

The dollars from 1795-1804 were .8924 silver. Would these have an accurate reading on the Sigma? Anyone use a Sigma on early US silver coins? </p><p><br /></p><p>I would like to get one, but if it doesn&#039;t work on my older coins, I&#039;m not going to bother.[/QUOTE]</p><p><br /></p>
