<p>[QUOTE="GDJMSP, post: 1309656, member: 112"]It's not a rule, it's a simple matter of what is possible. Dies are polished on a large, spinning zinc disk - many times larger in diameter than the die. So any die polish lines transferred to a die from that disk are always - virtually straight (it's an arc really but the arc is so shallow that you can't see it), all running in the same direction, and very consistent in their spacing and depth. They can never crisscross. They are also typically very fine, shallow lines. But they can vary in this regard, sometimes they are coarser than on another coin. Length may vary from short to long. And they are only found in the fields.</p><p><br /></p><p>There are basically 3 types of lines that can found on a die. 1 - die polish lines, 2- die scratches, 3 - flow lines caused by wear to the die.

[QUOTE="GDJMSP, post: 1309656, member: 112"]It's not a rule, it's a simple matter of what is possible. Dies are polished on a large, spinning zinc disk - many times larger in diameter than the die.

They can never crisscross. They are also typically very fine, shallow lines. But they can vary in this regard, sometimes they are coarser than on another coin. Length may vary from short to long. And they are only found in the fields. There are basically 3 types of lines that can found on a die. 1 - die polish lines, 2- die scratches, 3 - flow lines caused by wear to the die. All of these have different characteristics. And if you know what those characteristics are you can recognize one from the other when you see them on a coin. The characteristics for die polish lines I have described above. Die scratches are typically short. They may be curved, straight, or jagged and of varying depth. And they are almost always found close to the devices or in protected areas like inside letter or numeral loops. And they can be found in the fields or on the devices. Wear lines (from metal flow) on a die are always straight. They can vary greatly in depth and spacing, even on the same coin, and can be found anywhere in the fields. Since you can find all of these on a die you can also find all of them on a coin. Sometimes you can find all of them on the same coin, it's common even to do so. But you can also find other types of lines on a coin. On a coin you also find metal flow lines - which are entirely different than those found on a die. Flow lines on a coin are always straight, very fine, and very uniform in both depth and spacing. You can also find scratches - caused by almost anything, even another coin. And they can be all shapes, sizes, and depths. Scratches on a coin can leave behind raised metal as well as incuse marks. Hairlines can be found on a coin. They are typically very fine, shallow lines. Some you can't even see with the naked eye. They can be straight, curved or even jagged. They can be long or short. They can all run one direction or they can crisscross. They can be quite coarse at times, or both coarse and fine, and like scratches they can leave raised metal as well as incuse marks. And they can be caused by virtually anything from rough handling to harsh cleaning. It is important to note that many collectors, dealers, and even the TPGs, can and often do confuse one or more of these types of lines a coin for another. So, in a nutshell, that coin has a mixture of several different types of lines on it. Many of them are hairlines. And because of that it is not deserving of that grade.[/QUOTE]
