<p>[QUOTE=&quot;Tamaracian, post: 5749607, member: 23122&quot;]Hi Condor.&nbsp; Your observation is correct for most Analyzers out in the field.&nbsp; Most of the original generation, and current lower-end XRF Analyzers were/are limited to the depth of 8 to 15 um depending upon the beam strength and spot size; more up-to-date ones can go to 60 um and also have ED capability that can measure up to 5 layers of plating, and with either interpolation or a 2nd measurement, also the base metal.</p><p><br /></p><p>I was trying to suggest that XRF could be a valuable, non-destructive tool in the identification of metal composition, and therefore, could <i>help</i> to determine if a coin was fake or not--I just didn&#039;t go into very much detail on what results might be expected with any particular coin.[/QUOTE]</p><p><br /></p>
