<p>[QUOTE=&quot;Rick Stachowski, post: 2836037, member: 42872&quot;]Maybe this will help out .</p><p><img src="http://www.doubleddie.com/img/content/203906_203910.gif" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p>A Class IV doubled die is produced when the centers of the hub and die are not in alignment during one of the hubbings.&nbsp; Either the hub or the die will be &quot;off-center&quot; or &quot;offset&quot; with respect to the other.&nbsp; That is why the class received the name &quot;Offset Hub Doubling.&quot;</p><p><br /></p><p>For those familiar with error coins, the setup is very much like that which produces the error coin known as a &quot;misaligned obverse die&quot; error.&nbsp; Here, when the dies are set up in the coining press their centers are not directly opposite each other as they should be.&nbsp; The obverse die is slightly offset.&nbsp; When the planchet comes in and rests on the reverse die (older press setup) and is then struck by the obverse die, the reverse will be normal but the obverse will be slightly off center.</p><p><br /></p><p>As a result of the off-centered alignment between the hub and the die for one of the hubbings, overlapping images or doubling will occur. All of the doubling will be spread in the same direction on the die and thus on all of the coins struck by that die.</p><p><br /></p><p>To illustrate the effect we took the illustration of the obverse of a 1967 Lincoln cent (Figure 1) and made a transparency of it.&nbsp; We took the transparency and placed it over Figure 1 so that they were perfectly aligned.&nbsp; We then moved the transparency slightly to the north to create the image seen in Figure 2.&nbsp; It is a perfect example of the type of doubling seen on a Class IV doubled die.</p><p><br /></p><p style="text-align: left"><img src="http://www.doubleddie.com/mediac/450_0/media/Figure$201$201967$201c.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p><br /></p><p>Figure 1 - <i>This is the illustration of a 1967 Lincoln cent.&nbsp; It represents what would be seen on a die after the first hubbing.</i></p><p><br /></p><p style="text-align: left"><img src="http://www.doubleddie.com/mediac/450_0/media/Figure$203$201967$201c$20$20Class$20IV$20Doubled$20Die.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p><br /></p><p>Figure 2 - <i>This is the doubling that resulted when we made a transparency of Figure 1.&nbsp; We then placed it over Figure 1 and shifted it slightly to the north.&nbsp; The result was Class IV type doubling all spread in the same direction.&nbsp; This is exactly how Class IV doubled dies were produced.</i>[/QUOTE]</p><p><br /></p>
