<p>[QUOTE=&quot;GDJMSP, post: 1554246, member: 112&quot;]Not true Sam. A finished coin is always thinner in the fields than the unstruck planchet was. The metal the fills the devices and the rim has to come from someplace, and it comes from the the fields. Thus making the fields thinner than they were.</p><p><br /></p><p>The reason they use an upset mill on type 1 planchets to make them type 2 planchets is because striking pressure would have to be much higher if they did not. Otherwise the rims would not form correctly. And if pressure was higher the dies would not last.</p><p><br /></p><p>As everybody knows, when a coin is struck the metal flows. And when the metal flows the metal becomes thinner. The reason the metal flows is because it is literally squeezed, squished,&nbsp; between the 2 dies.[/QUOTE]</p><p><br /></p>
