<p>[QUOTE=&quot;desertgem, post: 1755608, member: 15199&quot;]First non-cents is correct that it is mechanical doubling, not a DD. However, you are correct , IMO, that the image is not exactly flat, it shows shearing as the die moved away from the strike. Not straight up, as normal MDD, but slightly sideways instead, but still MDD.</p><p>&nbsp;</p><p>If you like the search for varieties, I recommend to not use a USB microscope/LED lighting, because it is very difficult to distinguish glare from DD, or any other kind of error or variety. I use stereozoom scopes, and shoot through one of the eyepieces to get a sharper and more variable lighting arrangement. More costly, but much more versatile and will last a lifetime. I have used mine for about 30 years. With such a setup, I have had good success using a canon point and shoot with a macro setting and Image stabilization. Jim[/QUOTE]</p><p><br /></p>
