<p>[QUOTE=&quot;SuperDave, post: 2369885, member: 1892&quot;]Fair enough. I have to disassemble the OP&#039;s video - I want to capture a couple frames where it sure looks like at least a few of the lines are visible on the reverse, and process them for more clarity if possible to think about things, which I lack the time to do tonight - but I&#039;ll offer a couple tidbits first. The initial tidbit is, if you read what I&#039;ve posted, I have not referred to this coin as &quot;harshly cleaned.&quot; I&#039;ve used the term &quot;brushing,&quot; true, but near as I can tell I haven&#039;t called it cleaned. If anyone thinks that&#039;s my rock-solid conclusion, I have chosen my words wrongly.</p><p><br /></p><p>That&#039;s because I&#039;m not yet sure if mechanical cleaning is what did this. That is the working theory, but a couple things are still unclear to me about it.&nbsp; I&#039;m just sure it&#039;s not what you think it is, and here&#039;s why (I&#039;m repeating myself, but whatever):</p><p><br /></p><p>I don&#039;t believe the visible lines are much different on the devices, just differing somewhat in appearance because the inside of the devices (recessed on the die, of course) are as-pressed by the working hub and unpolished. It&#039;s physically impossible to polish them. Their surfaces are therefore much &quot;rougher,&quot; used in quotes because they&#039;re hardly rough themselves. All the same this point is moot to me because I can see the artifacts of whatever happened here just as heavily passing through the devices - including the rays - as the fields.</p><p><br /></p><p>All I need to disprove your theory, though, is to refer you to the sun on the obverse, and ask (again) how you&#039;d manage to get the tool evenly to the inside edge of a can in one smooth stroke, as the lines crossing it appear. It&#039;s just_not_possible, man, and arguing against that - which your theory requires - is pretty much untenable despite the fact you&#039;re doing it. And the rays? Um, no, not at all. You&#039;d be lucky to get a mark on them at all.</p><p><br /></p><p>I haven&#039;t wrested all the information possible from the video yet, but I still don&#039;t think all those lines are there in it, and these are two separate states of one coin. Sure looks to me like the toning is scrubbed off. For the record, I&#039;m thinking whatever hit it was more spongiform than &quot;brush&quot; in nature. And likely hit both faces simultaneously, in a (viewed from the obverse) southeast-northwest direction. Emery cloth in fairly large hands could probably do it, thumb and the sides of the first finger.</p><p><br /></p><p>And so far a damaged working hub hasn&#039;t been eliminated from my differential either. They&#039;d have to have caught it quick or there&#039;d be a whole bunch more of these extant, and what I&#039;ve learned in almost 15 years of photographing coins would have to be altered drastically to allow for toning to form over such prominent lines, and I&#039;d have to believe that the toning is still there (I don&#039;t), but even a 0.001 probability is a non-zero probability.[/QUOTE]</p><p><br /></p>
