<p>[QUOTE=&quot;medoraman, post: 1129033, member: 26302&quot;]Doug, yes I agree that anythign longer than a second or two, and not rinsed immediately with pure water, will take the &quot;edge&quot; off a coin. That is the best I can describe what you refer too, the tiny microns on the surface have the highest luster, so dipping takes off the &quot;pop&quot; slightly of a fresh BU coin. Everyone remember that the cartwheel effect is caused by the melting on the surface during the strike, and is strongest at the surface, decreasing every atom down from there.</p><p><br /></p><p>I guess I didn&#039;t read on his post how long it was. I have never dipped a coin longer than a second unless it was already near basket case territory, (black toning).[/QUOTE]</p><p><br /></p>
