And in some cases, with a strong strike, there will be no planchet flaws.</p><p><br /></p><p>Think it all the way through Mike. If planchet flaws are present on a planchet, what is the one thing that can remove them ? Flowing metal is the only thing that can remove them. And what the causes the metal to flow ? The strike. Therefore the stronger the strike the more flowing metal you will have. And the more flowing metal you have, the fewer the planchet flaws you can have.</p><p><br /></p><p>With a weak strike however you have less flowing metal. And if you have less flowing metal then fewer planchet flaws will be obliterated and there will be more left on the coin.</p><p><br /></p><p>Now consider what happens when die wear comes into the picture. On new, fresh dies the details are sharp, clear, and well defined. And in order to fill those details, the recesses in the die, the metal has to flow. And on new fresh dies, since the details are sharp and clear, the metal has a harder time flowing around and over all of those sharp edges and into the recesses. </p><p><br /></p><p>But with die wear those sharp edges on all of the details wear down, they become smooth and rounded over, and when they are smooth it becomes easier for the metal to flow and fill the recesses because it has less resistance. And the more metal that flows, the fewer planchet flaws you will have. So it becomes possible for a weaker strike to remove just as many planchet flaws as a strong strike did previously. And if the strength of the strike is equal, then there will be more planchet flaws removed with worn dies than there was with new, fresh dies because the metal can flow easier.</p><p><br /></p><p>Bottom line planchet flaws can be affected (removed) by a strong strike or they can be affected by a weaker strike. But in some cases fewer planchet flaws will be affected (removed) by a weak strike.</p><p><br /></p><p>It all sounds very confusing, but when you think it all the way through it makes perfect sense.[/QUOTE]</p><p><br /></p>
