<p>[QUOTE=&quot;Electron John, post: 2900882, member: 84417&quot;]I own an analytical testing lab so I plan on using SEM/EDS to determine the exact metals in each of my 20 Hellers.&nbsp; One of mine look like it has areas which are copper and areas that are brass within the same coin.&nbsp; I want to do a study on the different metals used to make these coins.&nbsp; I have read they used a cannon from a ship they scuttled, copper pipes, brass from spent ammo, etc.&nbsp; But I only have four of these coins right now.[/QUOTE]</p><p><br /></p>
