<p>[QUOTE=&quot;predcarn, post: 156512, member: 6000&quot;]I have used one like this for many years, first professionally in research </p><p>and then later when I restarted coins. I purchased one from a supplier</p><p>used for $50. Here is one on ebay that is identical except for eyepieces.</p><p><a href="http://cgi.ebay.com/Vintage-Bausch-and-Lomb-Stereo-Microscope_W0QQitemZ110031045655QQihZ001QQcategoryZ48741QQssPageNameZWDVWQQrdZ1QQcmdZViewItem" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://cgi.ebay.com/Vintage-Bausch-and-Lomb-Stereo-Microscope_W0QQitemZ110031045655QQihZ001QQcategoryZ48741QQssPageNameZWDVWQQrdZ1QQcmdZViewItem" rel="nofollow">http://cgi.ebay.com/Vintage-Bausch-and-Lomb-Stereo-Microscope_W0QQitemZ110031045655QQihZ001QQcategoryZ48741QQssPageNameZWDVWQQrdZ1QQcmdZViewItem</a></p><p><br /></p><p>This stereo is a tank. There are prisms inside that can ( if dropped) get</p><p>out of alignment, but otherwise almost student proof. The dial on the top</p><p>is a 0.7-3.0 magnifier of the eyepiece power, which in this case is 20X, so </p><p>you would have a magnification ability of&nbsp; 14X to 60X. You can find</p><p>eyepieces on ebay often that are 10X, so you could then have 7X to 30X</p><p>which is what I have. One eyepiece mount is diopter adjustable so you</p><p>can get sharp vision in both eyes even though your prescription <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /> may </p><p>be different in each. The head can be removed from the focusing body </p><p>and rotated 180 degrees for easier working. It is missing the round plate</p><p>( white on one side and black on the other ) that you would place the</p><p>coin on to observe, but that can be replaced with whitecardboard. If you</p><p>can find the light source that is intended for this microscope, it fits in</p><p>the hole back from the eyepieces and focuses light right on the coin. I</p><p>notice that they give the disclaimer that they don&#039;t know if it works, but</p><p>a quick look at any coin would tell. The mirror would be of no value for</p><p>looking at solid subjects.
