<p>[QUOTE=&quot;WINS7, post: 25018, member: 1413&quot;]Because the US Mint no longer produces coins for other countries the likelihood of it being a wrong metal error is rather remote.&nbsp; Here are three things it could be.</p><p><br /></p><p>Today’s zinc planchets are copper coated, and when the copper solution in the vat gets low an odd thing can sometimes happen to it.&nbsp; The combination of copper and the thousands of zinc planchets that have been run through it plus a few that stay behind can change the copper solution to a brass-like solution.&nbsp; If blank planchets are plated with this solution before it is replaced, the result is a yellowish-green color plating.&nbsp; These are highly collectible.</p><p><br /></p><p><img src="http://www.jdsworld.net/images/1983brass_plated.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p>However, if your coin is a bright yellow instead of a yellowish-green brassy color then this is not what happened to your coin.&nbsp; I suggest that your cent has been exposed to extreme heat, which has basically combined the copper plating with the zinc.&nbsp; This is a common experiment in high school chemistry classes.</p><p><br /></p><p>Another thing that could make your cent bright yellow is someone plated it with gold.[/QUOTE]</p><p><br /></p>
