<p>[QUOTE=&quot;GDJMSP, post: 3322591, member: 112&quot;]Strictly my opinion of course, but I thought I already answered the why of it - because there is no practical way, stress practical, to measure it. </p><p><br /></p><p>But, I can put it another way if you wish, one that fits right in with what you have written above - because to do so would be splitting hairs <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /></p><p><br /></p><p><br /></p><p><br /></p><p>Hmmm, OK - except for one thing. The author of the article referred to forgot to mention something of great importance. Something that also fits right in with your apparent desire to exercise microscopic examination of such things. Namely that yes, any scratch or hairline does produce an incuse line. But, at the very same time they also produce a raised line right alongside the incuse line. This is because the displaced metal has to go someplace and that someplace is right alongside the incuse line. Furthermore, he also forgot to mention that when die polish lines are present on a coin, they are also composed of a combination of raised lines and incuse lines, for the very same reasons. </p><p><br /></p><p>Lastly, I would suggest that of you wish to carry things to the extreme that numismatists need scratches and hairlines need to be measured and quantified, then you also better figure out a way to measure and quantify contact marks, abrasions, breaks in the luster (otherwise known as wear), altered surfaces, cuds, die chips, die cracks, die breaks, etc etc etc as well. Of course doing all of this would probably take days in some cases.</p><p><br /></p><p>OR - you could keep it simple, and practical, and simply have someone with the required experience do all of these things in about 5 seconds flat <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie2" alt=";)" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
