<p>[QUOTE=&quot;kevin McGonigal, post: 3109712, member: 72790&quot;]Not really experienced but I know precious metals are almost never encountered in a pure state and could not be made 100% anything in ancient times. What might be interesting to ascertain is what trace elements are more likely to be encountered in one region rather than another. That might enable us to pin down where in an empire the metal may have come from originally. Thus Dacian denarii silver coins might be differentiated not just by style from Spanish silver coins but by their metallic content. Though my father made a good living from metallurgy it is just a side interest for me. It may be possible, though,&nbsp; for authentication of ancient coins, perhaps coins from other areas and times, by discovering trace elements which could not possibly be in coins of that time from that part of the world.[/QUOTE]</p><p><br /></p>
