I only hope it also has not been beat to death on here before:</p><p>Prior to about 1990 the mint mark was applied by hand to the working die thus resulting in those varieties we love RPM&#039;s. A doublED die is just that, the die is doubled during the hubbing process The working die is prepared, (hubbed) THEN the mintmark applied. DoublED die occur before the maintmark is added - there fore a doubled die with a mintmark doubled in the same direction with the same sort of spread cannot (99 of 100 times) be a true doubled die. Conversely a mintmark cannot be a portion of a hubb doubled die until sometimes after 1990 because it was not even there during hubbing. The 1995-D DDO-003 has a mintmark being a portion of that doubled die because it was in place during hubbing.</p><p>There are exceptions as Potter noted on that 1969-S DDO-001 that was found last year had some die shift or mechanical doubling also along with the major doublED die. Earlier there were also doubled dies with RPM&#039;s also, RPM-100 and the 42-S come to mind. We also found 1957-D quarter that had a &quot;D&quot; in the wreath about a quarter inch away from the primary but later determined to be on a master die or master hubb - some of you may remember we found the same &quot;D&quot; on at least 4 different working dies. Wiles never thought it was one by I have a gem one and all you have to do is see it one time and you would flip-it&#039;s a &quot;D&quot;.</p><p>Now if you think this is complicated I gave the simplest of explanation as I could here.</p><p>Mechanical doubling as on this cent is only one of the criteria we use to help explain what type of thing occurred to cause the doubling.</p><p>But my ain&#039;t it fun!!!!!</p><p>&nbsp;</p><p>Ben &quot;took me ten years to get all this stuff straight&quot; Peters[/QUOTE]</p><p><br /></p>
