<p>[QUOTE=&quot;cpm9ball, post: 1205354, member: 24633&quot;]I don&#039;t believe that the blank is cut larger than the diameter of the actual coin. It&#039;s my understanding that the sole purpose of the upsetting mill is to squeeze the blank to partially form the rim so that when it enters the coining chamber, the metal can flow more readily outward from the center of the planchet and up/down to finish the rim. If the upsetting mill was bypassed, there would likely not be enough pressure to completely form the rim. The same would be true if the coin has a reeded edge (third side) and the metal has to flow into the recesses of the collar the full thickness of the upset rim.</p><p><br /></p><p>Chris[/QUOTE]</p><p><br /></p>
