<p>[QUOTE=&quot;mrbrklyn, post: 1007362, member: 4381&quot;]Chemical and structural analysis in industry is very advanced in serious scientific work.&nbsp; I&#039;m sure both markers, microscopic markings, and chemical traces in the parts per billion, can be found with the proper equipment.&nbsp;&nbsp; Whether it is economical or not, I can&#039;t answer.&nbsp; But when you start to understand the micronization of the latest waffers in CPU&#039;s for example, I&#039;m sure that rivals anything that dipping can do, and there is serious quality control in those waffers.</p><p><br /></p><p>This is largely besides the point.&nbsp; As Doug and others point out, the market allows for dips which have minimal affect.&nbsp; I&#039;d just say that if they want to find the dipped coins, they can, and I&#039;m pretty sure for coins reach nearly 100 years old or greater, that even more than 95% of the MS62+ coins have been dipped.</p><p><br /></p><p>The old time collectors dipped coins as a matter of normal activity.</p><p><br /></p><p>Ruben[/QUOTE]</p><p><br /></p>
