<p>[QUOTE=&quot;gxseries, post: 95770, member: 4373&quot;]Midas, I disagree with a few points. This will only work on VERY modern coins with no nonsense addictives, such as minor copper parasites. Another point that I disagree is with the use of laser scanner. Don&#039;t forget, a single scan is just a bloody flat 2D image. In order to get a better result, you need to have at least *several* scans at different angles to get a &quot;true&quot; image. Doesn&#039;t this happen in medicial industries for example to find out the size of a tumor? There is a good reason why photography are still kings when it comes down to contrasting sharp points. Afterall, if you wish to argue, our eyes does not see things in terms of 3D, but instead, our brain collects several hundreds of 2D images to make them look like 3D. Laser scanners may imitiate how we see things, but the thing is, our eyes still view objects a lot faster than what those scanners can do, except for accuracy. </p><p><br /></p><p>----------</p><p><br /></p><p>Back to the edging story, I have posted it at CU, and so I am copying it down here: </p><p><br /></p><p>There is no reason why slabs can&#039;t have the edge viewed. That is a reason why I avoided coins being slabbed at all costs because of this reason. A coin is 3D, not just two 2D images stuck together even if the edges are smooth. It is a ridicious pity that edges are not well represented. If you think about the 1700-1800s European coinages, have you realized how much effort they have put into engraving the edges of the coins to thwart people not to cut out precious metals? </p><p><br /></p><p>Taking the example of this from my Russian coin collection, </p><p><br /></p><p><img src="http://img365.imageshack.us/img365/203/edges1vi.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p><img src="http://img231.imageshack.us/img231/8207/edge20zj.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p>That alone is a small sample of what exists. I know that the British and French were leaders in such edging technology and has plenty of astonishing examples.[/QUOTE]</p><p><br /></p>
