<p>[QUOTE=&quot;Troodon, post: 140479, member: 4626&quot;]On #3, I assume you mean among coins that have any copper, lol, because there are several coins without any copper at all.&nbsp; Also, do you mean by the absolute weight of copper in the coin, or as a weight percentage of the coin?&nbsp; Also, are you referring only to US coins?&nbsp; If so the initial assumption is moot, since all US coins currently being minted for general circualtion have some copper in them.[/QUOTE]</p><p><br /></p>
