<p>[QUOTE=&quot;GDJMSP, post: 2293442, member: 112&quot;]Why ? You ever look closely at the top of a concrete floor ? It&#039;s made up of fine grains of sand virtually equidistant from each other. And anything scraped across that floor gets fine parallel scratches across it. And it would only have to move across the floor an inch or two. The same thing goes for the front edge of a shovel.</p><p><br /></p><p>As for lines being on the opposite side of the coin, planchet striations come the rollers squeezing the coin strip, with both sides of the planchet touching the rollers and moving in exactly the same direction at the same time. Often they only occur on 1 side of the planchet. But if they do occur on both sides of the planchet, the lines go in exactly the same direction on both sides - not in opposing directions.</p><p><br /></p><p>edit - Besides that, neither of these objections even remotely address the issues of the metal and the way it moves when a coin is struck that I explained in my previous post.</p><p><br /></p><p>Also, as I said, I&#039;m well aware that most people, including the TPGs, just consider these as planchet striations. So initial reaction to an actual explanation of what would happen to planchet striations during the strike are ignored for the most part. </p><p><br /></p><p>But once you stop and think, and use just a little common sense, it becomes that they simply could not be planchet striations.[/QUOTE]</p><p><br /></p>
