<p>[QUOTE=&quot;Insider, post: 2642601, member: 24314&quot;]I wish I could say for sure;but this is what I heard about conserving coins and it makes a lot of sense: </p><p><br /></p><p>Removing toning from a coin is MUCH MORE than a quick dip into various concentrations of EZ-est.&nbsp; The &quot;key&quot; to proper cleaning - leave no trace - is all in the preparation and the drying.&nbsp; For the best result, before a coin is dipped, its surface must be prepared. This is accomplished in various ways using various chemicals.&nbsp; The purpose of this preparation is to remove as much of the surface contamination/oxidation as possible before the end steps - the actual &quot;dip/neutralize/dry.&quot;&nbsp; Whatever they do, it must be a closely guarded process.&nbsp; I&#039;ve been told that the guys at NCS must sign a confidentiality agreement and cannot reveal what they do to conserve coins.</p><p><br /></p><p>I suspect the best chance of gaining a little &quot;inside&quot; information is to talk with former NCS employees.&nbsp; I have heard Brian Silliman speak on the subject of coin conservation and cleaning.&nbsp; The actual value of the coin makes no difference.&nbsp; A Silver Eagle gets the same attention as a Flowing Hair dollar.&nbsp; Only the method used and the pre-dip preparation changes depending on the coin&#039;s condition.&nbsp; </p><p><br /></p><p>When NCS started, I heard that on several Fridays a month. They stopped work on customer&#039;s coins and experimented with different methods and chemicals on &quot;junk&quot; coins to increase their knowledge and skills.&nbsp; Two former NCS employees are Brian (teaches classes) and Skip (teaches classes and does conservation at ICG).[/QUOTE]</p><p><br /></p>
