<p>[QUOTE=&quot;Cliff Reuter, post: 8218898, member: 115140&quot;]I agree that some of the modern doubling isn&#039;t confined to just the center or very dramatic.</p><p><br /></p><p>Doubled ears on Washington quarters &amp; shield cents, doorway headers on Jefferson nickels, and extra leaves on the Roosevelt dimes are the main source of DDR varieties.</p><p>A lot (most) of the DDR&#039;s are towards the center of the design for most of the modern denominations.</p><p><br /></p><p><br /></p><p>Here is an excerpt from John Wexlers doubleddie.com under &quot;doubled Dies&quot;</p><p>Link: <a href="http://doubleddie.com/58222.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://doubleddie.com/58222.html" rel="nofollow">http://doubleddie.com/58222.html</a></p><p>(The following quote is about 1/3 of the way down the page in the link above. It is just below the image of the &quot;hubbing press operator&quot; in the &quot;Single-Squeeze Hubbing Era&quot; section.)</p><p><br /></p><p>&quot;.... On October 1, 2009 I had the privilege of having a telephone conversation with George Shue, Senior Advisor in Manufacturing at the U.S. Mint.&nbsp; During this conversation the 2009-D Washington D.C. quarter with a major doubled die reverse came up.&nbsp; Mr. Shue noted that <b><u>the Mint was aware of this doubled die error and how it occurred.&nbsp; This particular doubled die resulted when a hubbing press operator stopped one of the single-squeeze hubbing presses to realign the hub and die and then restarted the hubbing sequence.&nbsp; In the process a rotational misalignment of images resulted.&nbsp; Mr. Shue further noted that the Mint was able to reproduce the error in a test to see what caused the doubled image originally.</u></b></p><p><br /></p><p>The conversation further revealed that the Mint was aware that even though it was contrary to policy, hubbing press operators were taking it upon themselves to sometimes stop the single-squeeze hubbing presses before the hubbing was completed to make adjustments, and then restarting the press to complete the hubbing.&nbsp; To prevent doubled dies like the major variety seen on the 2009-D Washington D.C. quarter from happening again, the Mint has installed “locks” on the hubbing presses.&nbsp; Now if a hubbing press operator stops the press before the hubbing is completed, they will be unable to restart the press until a supervisor comes to inspect everything to make sure that things are reset properly.&nbsp; The supervisor will then “unlock” the press so that the hubbing can be completed.&nbsp; So for now doubled dies continue to be produced despite Mint efforts to eliminate the die variety.&quot;</p><p><br /></p><p>If I get motivated and they start attributing varieties again I&#039;ll probably send this in for clarification. If that happens I&#039;ll share the results no matter how it turns out.</p><p><br /></p><p>Thanks for all the comments and input. I truly enjoy the discussions and learning more.[/QUOTE]</p><p><br /></p>
