<p>[QUOTE=&quot;bhp3rd, post: 542443, member: 16510&quot;]New thread, lets study classes of doublED dies one per week.</p><p>&nbsp;</p><p>This will help me as well as everyone else on here if they really want to learn about doublED dies.</p><p>&nbsp;</p><p>1st week Class I DoublED Dies</p><p>Rotated Hub Doubling</p><p>Examples: 1955 DDO #1, 1972 DDO #1970-S DDO #1 &amp; 1969-S DDO #1 all Lincoln cents.</p><p>With Class I doubled dies the doubling occurs when there is a rotation between the image on the die and the image on the hub.</p><p>When the hub and the die are aligned in the hubbing press to make the second, third or forth impression in the working die there is a slight rotation between the two.&nbsp; The rotation can either be clockwise or counter clockwise.&nbsp; Since the second hubbing will push the hub a little more deeply into the die than the first hubbing, the image from the second hubbing will be a bit stronger than that of the first hubbing.&nbsp; As a result it is possible to tell when looking at a Class I doublED die whether the rotation between hubbings was in a CW or CCW direction.</p><p>On Class I doublED dies, being caused by rotation, the strongest spread will appear on the design elements closest to the rim and decrease in a uniform manner as you move towards the center of the coin, (die).</p><p>(paraphrased from The Cherry Pickers Guild)</p><p>&nbsp;</p><p>&quot;&quot;&quot;As always remember and get it firmly in your head, a doublED die exists before a coin is ever struck and the resulting coin struck from a doublED die is then also called a doublED die&quot;&quot;&quot;&quot;&nbsp; It is never called a &quot;double&quot; die or &quot;double dyed&quot; or &quot;double die date&quot;&nbsp; or &quot;a double&quot; or D/D, D/D is and RPM (re-punched mintmark) and was not possible to be a portion of a true doublED die till the early to mid 1990&#039;s on Lincoln Cents.</p><p>&nbsp;</p><p>Next week, Class II doublEd dies![/QUOTE]</p><p><br /></p>
