<p>[QUOTE=&quot;SuperDave, post: 2599336, member: 1892&quot;]Am I correct in believing Ancients used hand-carved dies?</p><p><br /></p><p>More recent dies employed a Master Die (a negative just like the production die), machine-copied from a much larger original, which were then used to create positive-relief hubs (&quot;Working Hubs&quot;) from which the actual striking dies were created. These production dies (&quot;Working Dies&quot;) were impressed (while annealed) by the hubs, and it generally used to take more than one impression operation to get the design fully imparted. It&#039;s imperfect alignment between successive hub impressions which result in doubled dies.[/QUOTE]</p><p><br /></p>
