<p>[QUOTE=&quot;dougsmit, post: 3539505, member: 19463&quot;]Over the years I have recommended the use of a stereo microscope on several occasions.&nbsp; There are many variations and I am not at all in a position to tell you which to buy.&nbsp; The one I have was cheap and has not been sold for years.&nbsp; eBay is full of options.&nbsp; All seem to have one characteristic that seems obvious.&nbsp; The platform where you place the subject coin is flat and parallel to the lenses.&nbsp; I have discovered that I see more interesting things in better light using a small wedge of wood covered with a scrap of craft foam that changes the light angle just a bit.&nbsp; Turning the device on edge make examining the edges of the coin easier. I first designed this as an .stl file for a 3D printer but then decided this was easier and quicker done in wood with a saw and glue.&nbsp; If by the wildest chance anyone reading this finds this at all interesting, I would be happy to discuss it with them. </p><p>[ATTACH=full]940612[/ATTACH][/QUOTE]</p><p><br /></p>
