<p>[QUOTE=&quot;Kentucky, post: 1492734, member: 33176&quot;]Before you get the wrong idea, I do enjoy sparing with you.&nbsp; You are a really knowledgeable guy and I just enjoy tweeking you from time to time.&nbsp; I think the article I appended to a post points out correctly that if the film formed on a coin, which we call toning, exceeds the wavelength of the longest wavelength of light, we call it tarnish since it is no longer translucent.&nbsp; This just happens to be perhaps a thousand atoms of silver (if you call this a few atoms).&nbsp; Did you read the article, it really was interesting and really made sense.&nbsp; Also, anodizing is a commercial process that increases the thickness of the naturally oxidized surface of aluminum surfaces.&nbsp; Since anodizing involves oxidation of the aluuminum surface, it is now much of a stretch to say that ALL of my aluminum coins are anodized.&nbsp; You do raise a very interesting point in that I now wonder if there are any currency aluminum coins that are commercially annodized.&nbsp; Think I will search for that.&nbsp; Fun discussing things with you.[/QUOTE]</p><p><br /></p>
