<p>[QUOTE=&quot;desertgem, post: 2044246, member: 15199&quot;]There is some evidence that plating errors in the mint produced some brass colored cents, but how to prove a certain brass colored cent was made in the mint process? Anyone, and thousands of students do this experiment every year, one can change the color from copper to &#039;silver&#039; actually zinc color to brass ( a gold color). A few then keep the result, and others spend it to end up in change or rolls. Since the &#039;88 is a zinc core with a copper shell cent, a person could make hundreds of them if there was a premium. Photos would help. but see this url.</p><p><br /></p><p><a href="http://chemistry.about.com/od/chemistryhowtoguide/a/goldsilverpenny.htm" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://chemistry.about.com/od/chemistryhowtoguide/a/goldsilverpenny.htm" rel="nofollow">http://chemistry.about.com/od/chemistryhowtoguide/a/goldsilverpenny.htm</a>[/QUOTE]</p><p><br /></p>
