<p>[QUOTE=&quot;Jimski, post: 2749815, member: 77373&quot;]Back around 1986 when I started collecting coins.&nbsp; I was filling a Whitman folder of Lincoln cents, and I found in circulation, the two cents on the bottom of the following picture (the top coin is a color reference).&nbsp; I wondered if they came from the mint that way or if the color was post mint. </p><p>[ATTACH=full]629563[/ATTACH] </p><p>In 2015, while I was searching for information about all the hub changes of the Lincoln cents, I found this reference:</p><p>From:&nbsp; <a href="http://users.scronline.com/lockem/20thcentury.txt" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://users.scronline.com/lockem/20thcentury.txt" rel="nofollow">http://users.scronline.com/lockem/20thcentury.txt</a></p><p><i>This is Mike Locke&#039;s best attempt to date at a complete listing of all of the hub design changes to occur in US minor coins (non-gold) of the 20th century.&nbsp; ...</i></p><p><i>....</i></p><p><i>-1983,1985-D Brass plated zinc</i></p><p><i><i>Another planchet variety; this one a bit controversial, since the brass color can be simulated by heating a struck coin.&nbsp; Correct coins should be coin brass, the same color as pre 1982 cents; not bright yellow.</i></i></p><p><i><br /></i></p><p><i>According to the mint report on these, they should be classified as a mint error rather than a planchet type.&nbsp; The official explanation is that the planchets were overheated during annealing, resulting in zinc migrating into the copper (thankyou, Alan Herbert)</i></p><p><br /></p><p>Wow, the exact dates and mints I had set aside about 30 years earlier.&nbsp; And I had not set aside any other brassy cents … only these two.&nbsp; It can&#039;t be a coincidence, I finally had an answer after all those years.&nbsp; </p><p><br /></p><p>&nbsp;The 1983 was in a Whitman folder all those years, but I put in in a flip after reading the reference.&nbsp; I replaced the 1983 from a jar of cents that I squirreled away that many years ago.&nbsp; I found another slightly brassy 1983 in the jar.&nbsp; It’s not as dramatic as the first two … so I didn’t notice it then.&nbsp; Here is a photo of the second 1983 cent(in a replacement folder) . </p><p>[ATTACH=full]629567[/ATTACH][/QUOTE]</p><p><br /></p>
