<p>[QUOTE=&quot;GDJMSP, post: 2368715, member: 112&quot;]Die polishing and harsh cleaning both create raised and incuse lines on dies, harsh cleaning creates both raised and incuse lines on a coin. Even a simple scratch on a coin or a die creates a raised and incuse line or lines.</p><p><br /></p><p>Some folks don&#039;t understand that, or never realized it, nonetheless it is quite true. And there is a very simple reason it is true, it is because whenever metal is scratched (and that&#039;s what die polishing and harsh cleaning is - scratches) when whatever is doing the scratching and creating the incused line/s the metal that is being displaced by the scratch merely piles up on or both sides of the incuse line that is being formed thus creating 1 or 2 raised lines.</p><p><br /></p><p>This cannot be avoided, it happens every single time, because of the very nature of metal.</p><p><br /></p><p><br /></p><p><br /></p><p>I think you need to look at those pictures again. Are they parallel and similarly deep ? Yes. Do they all stop at the same distance from the devices ? Most definitely no. Some stop near the devices, some stop at the devices, and some continue onto the devices themselves and then on past them.</p><p><br /></p><p>I also think you need to read my original post more carefully and actually think about what I said, without just dismissing it. And, I&#039;m still waiting for you tell us what you think happened and describe how it happened for us. As of yet you haven&#039;t said a word about that.[/QUOTE]</p><p><br /></p>
