<p>[QUOTE="mpaulson, post: 217187, member: 2639"]I have done this experment many times and the results don't look like this coin, they are all mutted with way less details, just scrapped the edge of the coin,,show no evidance of platting either. I am fairly convinced it's Zinc, I have an ultra micrometer I can also use on it tommarow for thickness and diameter.[/QUOTE]</p><p><br /></p>
