<p>[QUOTE=&quot;GDJMSP, post: 2618588, member: 112&quot;]The simple and very obvious answer is - because they are not die polish lines.</p><p><br /></p><p>There&#039;s several basic things that must be understood. First, die polishing is done to remove imperfections from the die, that is its very purpose. Second would be that there are two completely different times when dies are polished: 1, before they are ever used, and at this point there are very, very, rarely ever any die polish lines visible to the naked eye or minor magnification; the 2nd time when dies are polished is after the die has been used for a while and it has become damaged or worn. It is then removed from the press, returned to the workshop and re-polished. 99% of all die polish lines that are visible on a coin occur during re-polishing. And they are only visible because the re-polishing was done incorrectly and/or incompletely.</p><p><br /></p><p>Next you have to understand that die polish lines are not circular in nature, to the contrary, they are for the most part straight and parallel lines, or at least they appear to be straight to our eyes. In reality there is an arc to them but the arc is so very slight that it is difficult to see. This is due to the nature, the method, of die polishing. In diameter the die is small, a silver dollar is less than 1 1/2 inches (38mm). But the plate, the disk that is used to polish the dies is large, say 10 times that of the die. This results in a small degree of arc of the disk coming into contact with the die. And a small degree of arc of a large circle appears to be almost a straight line. And the smaller the degree of arc, the straighter it appears to be. This is all simple geometry.</p><p><br /></p><p>Now rarely do we ever see die polish lines that go across an entire coin, in other words rarely do they ever stretch from side of the diameter of the coin to the other side. Typically we only see bits and pieces of them, and those bits and pieces appear to be virtually straight lines.</p><p><br /></p><p>It must also be understood that die polish lines are shallow, often very shallow. And when a die is first used after re-polishing is when those lines will be their most visible. But with use, because of metal flow when the coins are struck, die polish lines are worn away by that metal flow. So very soon there will be no die polish lines visible on the coins. And they may wear away in one spot soon than another, and this adds to, indeed causes, the result of us only seeing bits and pieces of them in various places on the coins.</p><p><br /></p><p>Other things that must be understood when we are examining the coins where they are said to have die polish lines, is that it is all to common for there to be die polish lines, die scratches, and just plain scratches on the coin - all 3 on the same coin at the same time. Now die polish lines, and die scratches, will both be raised lines on the coin. The die polish lines (alone) will be straight and parallel. The die scratches can run in any direction and not only criss-cross each other but also criss-cross the die polish lines. And because both sets of lines are raised, it is assumed, <u>incorrectly</u>, that they are all die polish lines. Then throw in some scratches on the coin from rough handling, and even an MS coin can be roughly handled, and you now have 3 different sets of lines, all caused by entirely different things, and all on the same coin at the same time.</p><p><br /></p><p>Now granted, the scratches on the coin are incuse, or so most people think. But in reality any scratch on a coin creates not only an incuse line but a raised line right beside it, and sometimes a raised line on each side of the incuse line. And because they are mixed with and criss-crossing at least one and often two different sets of raised lines, it becomes very difficult for the - I don&#039;t know how else to say it - uneducated eye to distinguish those 3 sets of lines from each other. And this difficultly is compounded by that fact that scratches on a coin are both raised and incuse.</p><p><br /></p><p>The key to understanding all of this is a quite simple concept, and that is that it is physically impossible for die polishing - stress die polishing - to create lines that criss-cross each other. Therefore it becomes a fact that any raised lines on a coin that do criss-cross had to have at least two different sources/causes, and thus they cannot all be die polish lines.</p><p><br /></p><p>And there&#039;s no question in this, there is no room for doubt, this is simple cause and effect. It is all, geometrical, mathematical, and physical. And once you understand that you know that it must be so.</p><p><br /></p><p>Now Insider says he wants to &quot;see things&quot;. Well OK, let&#039;s see things. Here&#039;s a picture of a die that has die polish lines on it, die wear on it, and die scratches on it - all on the same die. It&#039;s even got some die cracks on it. And they are all very easy to differentiate from one another.</p><p><br /></p><p>[ATTACH=full]574128[/ATTACH]</p><p><br /></p><p><br /></p><p>Now you can plainly see the die polish lines are most easily visible in the center of the die. And you can also easily see that they are exactly as I described above, they appear to be virtually straight but you can even see the slight arc. And they are all parallel and do not criss-cross at all. The die scratches on the other hand are also plainly visible and easily differentiated once you know what you&#039;re looking at. As is the die wear.</p><p><br /></p><p><br /></p><p>Here&#039;s another one with die polish lines, die scratches, die wear, and die cracks.</p><p><br /></p><p><br /></p><p>[ATTACH=full]574129[/ATTACH]</p><p><br /></p><p><br /></p><p>The same can be said about this one as what I said above.</p><p><br /></p><p><br /></p><p>And lastly, here is a picture of die with a closeup of die wear, and even a couple of die scratches.</p><p><br /></p><p>[ATTACH=full]574130[/ATTACH]</p><p><br /></p><p><br /></p><p>And here is a picture of the same die, in its entirety, and you can plainly see some die polish lines in the left hand fields at about 9 o&#039;clock. And they are also as I described above. Straight and parallel, no criss-crossing whatsoever. But if you zoom in you can see some patches of die scratches in various places.</p><p><br /></p><p><br /></p><p>[ATTACH=full]574134[/ATTACH]</p><p><br /></p><p><br /></p><p><br /></p><p>It is things like this that explain why I say what I say. I don&#039;t just make this stuff up. And if that flies in the face what we have been told over the years, then so be it. What I am saying is true, and it&#039;s pretty dang hard to argue about it once you understand.[/QUOTE]</p><p><br /></p>
