<p>[QUOTE="ziggy9, post: 2018679, member: 8360"]Wrong.</p><p>The most common place for pre 1990 zinc cents to rot is around the mintmark. Because the mintmark is hand struck into the working die it is often higher relief than the rest of the coin, leading to more chances of the copper plate splitting at that point. Once there is a split in the plating to allow the atmosphere in the zinc rot begins. I have seen many cents with the rot around the mintmark, several so bad that the mintmark actually fell off the coin.[/QUOTE]</p><p><br /></p>
