<p>[QUOTE=&quot;FWThomas, post: 2230436, member: 75119&quot;]Couldn&#039;t help but read up on this because it concerns me, being new to the coin collecting hobbie I&#039;m terrified of making this mistake. But I do have a little experience with Chinese counterfeits. I work in the energy field for the utility company&#039;s and it looks like you guys are having the same problem we had about 5 years ago, not with coins but counterfeit bolts. It got so bad we couldn&#039;t tell a good bolt from a bad bolt, and when you have a high pressure steam turbine at 30 tons spinning at 3000 rpm, you need to know. My department is what&#039;s called NDT &quot;Non-Destructive Testing&quot; we test things without actually destroying the parts intended use. In short do you know if any company&#039;s have used Nuclear Analyzers to determine a materials make up. Every material responds differently &quot;measurable difference&quot; when exposed to a radioactive source, you may be able to use something like a XRF Analyzer made by Olympus to verify a coins material make up. Olympus has awesome customer service and most of the time all you half to do is call them maybe send them a known good coin and one counterfeit and they will let you know if it can be done. Just food for thought, we use one of these gauges in our shop and we haven&#039;t&#039; had a problem in several years.[/QUOTE]</p><p><br /></p>
