<p>[QUOTE=&quot;desertgem, post: 3067643, member: 15199&quot;]Quote:</p><p>&quot;When the Mint switched to the single-squeeze hubbing process, the hub and die set-up in the hubbing press changed for the first hubbing which now would be the only hubbing.&nbsp; <b><u>The hub is no longer locked into the top of the hubbing chamber. </u></b>&nbsp; ( My bolding) The die blank is placed into the well of a collar placed in the bottom of the coining chamber.&nbsp; The hub is also placed into the well of the collar so that the face of the hub is resting on the conical point of the top of the die blank.&nbsp; <span style="color: #ff0000">Since the diameter of the well in the collar has to exceed the diameter of the die blank and the hub (so that the die blank and hub can be inserted into and removed from the collar, and so that the hub can be pushed downward into the die),&nbsp; &nbsp; <span style="color: #0080ff"><b> there is “play” in the collar well.&nbsp; It allows for some horizontal movement between the hub and the die when the hubbing process begins.</b> ( my bolding )&nbsp; There is even the possibility of some rotational movement.&nbsp; More importantly for this discussion, the hub will be tilted with respect to the die prior to the start of the hubbing since it is sitting unrestrained on point of the cone of the die blank in the collar well.</span></span></p><p><span style="color: #ff0000"><span style="color: #0080ff"><span style="color: #000000"><u><b> <a href="http://doubleddie.com/203990.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://doubleddie.com/203990.html" rel="nofollow">http://doubleddie.com/203990.html</a></b></u></span></span></span></p><p><br /></p><p><br /></p><p><br /></p><p><span style="color: #ff0000"><span style="color: #0080ff"><span style="color: #000000">Why do they use the &quot;classes&quot; that are used for the real doubled dies and say since the outcome looks like a doubled die, effect we call it so, even though if you read the section above in blue, it is &quot;play&quot; in the single squeeze process that causes them....</span></span></span></p><p><br /></p><p><span style="color: #ff0000"><span style="color: #0080ff"><span style="color: #000000">This is called mechanical doubling originally, and it is still mechanical doubling, but it seems profitable to the gurus to convince people it is the same cause.&nbsp; I have a feeling that many collecting these have no idea of the difference in processes. If people actually do know and don&#039;t really care, that is fine. To me, it is like relabeling a Vespa with the Harley Davidson insignia to advertise and sell. IMO of course.
