<p>[QUOTE=&quot;Contrarian, post: 4904054, member: 98206&quot;]Hello Insider,</p><p><br /></p><p>Another great question.</p><p><br /></p><p>As Lehigh 96 pointed out, the darker marks are luster grazes or frost breaks. The contrast with the lighter surrounding areas is a light phenomenon, such as can be seen on a cameo proof, for example. They are simply the absence of luster.</p><p><br /></p><p>As for the more complicated &quot;scuff&quot; marks, they are certainly not random and are too symmetric to have been made by anything other than a machine or someone using a tool, such as a file. They are too deep and curved to be album-slide marks.</p><p><br /></p><p>I don’t think a machine is responsible for this however, because if you look closely at the marks you can see that they were caused by two distinct strokes that begin and end at different points. A coin-counting machine wouldn’t do that.</p><p><br /></p><p>Did these marks occur in the mint, or afterward? Which basically boils down to the question of whether they are incused or raised.</p><p><br /></p><p>Frankly, they look raised to me, although it’s not always easy to distinguish between incuse and raised just judging by reflection. Moreover, there are also little bumps within the scuff marks that also reflect the light in the same way as the lines.</p><p><br /></p><p>So I believe we are dealing with tooling marks. There was something in the die which someone tried to remove with a file. And if you look under the scuff/file marks, you can see traces of raised areas and bumps that normally shouldn’t be on Miss Liberty’s chin. Perhaps due to a rusted die.</p><p><br /></p><p>To get back to your initial question, I don’t know what these horizontal lines are called.</p><p><br /></p><p>Contrarian[/QUOTE]</p><p><br /></p>
