<p>[QUOTE=&quot;Nefarius Purpus, post: 10488953, member: 116505&quot;]I am not a metallurgist but our suggestion is that every coin had its own unique clay mould, broken upon cooling. These moulds were made from common hubs. Every mould would have its own shape. As for separation of metals from the complex ore, this was done by local industry. Separation of gold and silver was difficult (see Pliny, and archaeological discussion of &#039;litharge rolls&#039; in our cited literature). A bit of copper could have been added at any time. </p><p><br /></p><p>As for the filling line I suspect it was above the coins and cleared up later, but none of us are experts and we woud welcome input from anyone who knows about casting gold.[/QUOTE]</p><p><br /></p>
