<p>[QUOTE=&quot;FWThomas, post: 2230597, member: 75119&quot;]There are many different methods of NDT, I&#039;m not going to bore you with the details. But the XRF probe which is new to the world of NDT would probably cost around 20 K, if I where to guess. However I believe there was an article here on lead cores in gold coins? If that&#039;s the case Eddy Current could be used to detect a material that was not homogeneous, Eddy Current technology has been around for years you can pick up a small hand held probe for couple hundred dollars. Like I said earlier I&#039;m new to coin collecting, never occurred to me to use NDT on coins, its main purpose was for the Aerospace, Energy, Oil &amp; Gas industries. Going to a coin show this weekend, I have a friend I&#039;m sure has a few counterfeits laying around, he keeps them to show folks just how easy you can be fooled. I&#039;ll look into to it.[/QUOTE]</p><p><br /></p>
