<p>[QUOTE=&quot;mikediamond, post: 51022, member: 1859&quot;]It&#039;s discolored.&nbsp; It&#039;s impossible to say where the discoloration occurred.&nbsp; Even if it occurred in the Mint, it&#039;s difficult to determine the cause.&nbsp; Even if the color corresponds to the range of variation generally accepted for &quot;sintered plating&quot; errors, the entire category is questionable.&nbsp; Same goes for &quot;copper wash&quot;.&nbsp; Nickels and clad coins do emerge with a copper color and sometimes with thick, peeling copper plating.&nbsp; Such errors, while fairly common, are poorly understood.&nbsp; Especially the nickels.&nbsp; Quite a few are seriously underweight, which is exactly the opposite of what you&#039;d expect with an added layer of copper.&nbsp; Some feature flaking and peeling outside the copper area.&nbsp; Some show peeling of composite copper/Cu-Ni metal.&nbsp; Some show black or brown underlying metal.&nbsp; It gets more bizarre than that.[/QUOTE]</p><p><br /></p>
