<p>[QUOTE=&quot;cladking, post: 67542, member: 68&quot;]Small round disks of metal are punched from a large flat strip of metal in the</p><p>blanking press.&nbsp; These are often referred to as type 1 planchets.&nbsp; These are </p><p>a little larger than the coin they are intended to make so that they can be stood </p><p>on end and forced between two spinning rolls.&nbsp; These rolls squeeze the coin down</p><p>to the proper diameter for minting.&nbsp; The planchets are now called type 2 planchets </p><p>after going through the upsetting machine.&nbsp; The purpose of upsetting is to bunch</p><p>up a little extra metal around the edge of the planchet so that the rim of the coin</p><p>can form during the strike.&nbsp; </p><p><br /></p><p>Planchets go into large totes and transferred to the coining presses.&nbsp; The old style </p><p>press simply pushed a die downward into the planchet with the reverse die under-</p><p>neath.&nbsp; The metal acts like a fluid under the extreme pressure generated and flows</p><p>into the recesses of the two dies.&nbsp; There&#039;s the third die or collar which is there to</p><p>stop the metal from flowing outward.&nbsp; </p><p><br /></p><p>Newer presses are actually horizontal and have four obverse and four reverse dies.</p><p>They strike at very high speed.[/QUOTE]</p><p><br /></p>
