<p>[QUOTE=&quot;Oldhoopster, post: 4053838, member: 84179&quot;]Please provide corroborating data on how you are sure you have a missing clad layer.&nbsp; I am surprised that you haven&#039;t provided weights, thicknesses , and strike characteristics, since these are easy data that supports your claim.</p><p><br /></p><p>I am also very interested in your comment regarding the deterioration of the outer clad layer?&nbsp; Are you suggesting that this deterioration occurred during the minting process?&nbsp; The 75Cu25Ni alloy is a pretty stable alloy.&nbsp; You can see discoloration during certain environmental conditions (I&#039;m not sure if it&#039;s due to copper enrichment of the surfaces, or something else), but for the entire layer to deteriorate? Interesting theory.&nbsp; Do you have any metallurgical info to support this?[/QUOTE]</p><p><br /></p>
