<p>[QUOTE=&quot;mrbrklyn, post: 102052, member: 4381&quot;]You CERTAINLY can tell its dipped if you look close enough.&nbsp; We had a whole discussion on the affect of dipping on the microscopic flow lines of the metal.&nbsp; As a fact, dipping is a chemical reaction with a reducing agent or an acid designed to remove part of the coins material.</p><p><br /></p><p>This is damage.&nbsp; There is no other way to dispassionately look at it.&nbsp; All resortoration damages the object.&nbsp; Its the first rule of resoration.&nbsp; Everything else stated in this thread about dipping and cleaning is opinion, except this statement and related statements about the actual chemical and physical results of dipping.&nbsp; Dipping and &quot;cleaning&quot; a coin damages a coin EVERY TIME.&nbsp; Your using a chemical to react with the coin and remove a layer that you don&#039;t want.&nbsp; If it didn&#039;t, nobody would do it.</p><p><br /></p><p>Toning is the oxidation of a coins surface from Au + O2 ==&gt; AuO2</p><p><br /></p><p>How in the world can you remove this without removing part of the coin?&nbsp; Do you really think this can&#039;t be spotted under a microscope?&nbsp; You can try to reduce the material back to plane silver but don&#039;t bet on keeping the surface the way it was.&nbsp; This is not theory.&nbsp; Its not about what someone might like or prefer.&nbsp; Its about the physical and chemical processes that stress the coin.</p><p><br /></p><p>Real cleaning of a&nbsp; material is a Physical event only.&nbsp; Like removing grease from a shirt with soap.&nbsp; And even that is damaging to the shirt.</p><p><br /></p><p>Ruben[/QUOTE]</p><p><br /></p>
