<p>[QUOTE="ikandiggit, post: 1018613, member: 16269"]It's taken me a long time to see the differences because when I started collecting, I used an old guide book that listed some of the machine doubling as "re-cut" devices when in actuality they weren't. The term "shelf-like" is about the easiest way to establish the machine doubling where the device is sheared therefore causing a secondary flat image. In true doubling the hub is struck twice which accounts for the secondary image to appear on the same plane as the primary device. When you look at the famous 1955 cent, you see how both images are level. That example is extreme but if you tighten up the two images (strikes) you'll understand how that type of doubling is different from machine (sheared) doubling. You'll also see the notching which differentiates it from machine doubling.</p><p><br /></p><p>I hope that doesn't sound like gobble-de-gook.:smile[/QUOTE]</p><p><br /></p>
