<p>[QUOTE=&quot;GDJMSP, post: 2037499, member: 112&quot;]There are many different things besides a harsh cleaning that can cause scratches and hairlines on a coin. Simple rough or careless handling causes them. Sliding a coin across a counter or table can cause them, wiping a coin with a cloth can cause them, even wiping a coin with your finger can cause them. The possible causes are pretty much endless.</p><p><br /></p><p>It is also important to realize that it is extremely common to find coins where only the fields, or only the devices, as well as both, will show hairlines and light scratches from rough handling and or harsh cleaning. And it is even more important to realize and understand that any and every scratch or hairline on a coin, regardless of its cause, creates both a raised line and an incuse line on the surface of the coin. This is simple physics, you cannot have one without also having the other.</p><p><br /></p><p>I&#039;m saying this because people use certain diagnostics to determine if the lines on a coin are the result of die polishing or post strike damage. But some of the most commonly used diagnostics will not always determine one from the other. So it then becomes important to know what diagnostics will determine one from the other. And they are fairly simple.</p><p><br /></p><p>Lines caused by die polishing cannot criss cross, they are always parallel to each other - always. That said, it is common to find lines on a coin that were caused by both die polishing, and post strike damage (scratches and hairlines caused by other things). And rather obviously the post strike lines can criss cross the lines caused by die polishing. But when that is seen, the lines caused post strike are often ignored and incorrectly attributed to the die polishing as well.</p><p><br /></p><p>Lines on a coin caused by die polishing also have a certain look that is distinctly different from lines caused by post strike damage. It is hard to explain in words and is something that is best learned by in hand experience. But the trained eye can easily distinguish one from the other.</p><p><br /></p><p>That said, if you look at the 2nd and 3rd picture of the OP&#039;s coin you will see spots above the horse&#039;s legs and below its head. It is my belief that there were probably similar spots elsewhere on the coin that somebody tried to wipe off the coin by using a cloth, resulting in the lines seen on the coin in various places.</p><p><br /></p><p>So no, those lines were not caused by die polishing.[/QUOTE]</p><p><br /></p>
