<p>[QUOTE=&quot;desertgem, post: 3594179, member: 15199&quot;]The reason the magnet only sticks the edge is that the edge was exposed steel so only the copper layer there, but the rest of the coin has a zinc layer ( the edge does not ) and then a copper layer over that so thicker. What ever you do now is probably a waste of money, but you can put it away and wait a few years until instrumentation gets better and testing cheaper.&nbsp;&nbsp; Jim[/QUOTE]</p><p><br /></p>
