<p>[QUOTE=&quot;rascal, post: 1488541, member: 29239&quot;]It is easy to tell that this coin has become toned to a copper color on one side and has started to tone on the other side. it is not missing a clad layer , our newer coins just tone like this. I wish they didn&#039;t do this but they do. I have over a hundred of the 2005 ultra detached leg bison nickels that are in ANACS slabs and they all are now toned to look just like copper. </p><p><br /></p><p>I did a experiment with some of the new state quarters by washing them in warm water and soap then rinsed them off and they have remained bright and shiny while the unwashed ones turned to the copper color. I believe this confirms that the mint is using something different to wash the new planchets and this is what causes this copper color toning.</p><p><br /></p><p>If the new coins are sealed in the cello mint packs and protected from the air they also sometimes stay bright and shiny. so this has something to do with the reaction from whatever wash and rinse the mint is using and exposure to the elements of the air exposure.</p><p><br /></p><p>from now on I will wash and dry all of my coins or dip them in acetone before sending them in for grading.[/QUOTE]</p><p><br /></p>
