<p>[QUOTE=&quot;SuperDave, post: 2398369, member: 1892&quot;]Quick, simplistic rundown of the process (at least back then):</p><p><br /></p><p>Artist sculpts an exact rendering of the coin much larger than original for ease of production. This is copied via reducing machine onto a steel Master Hub. Both are &quot;positives,&quot; just like the coins will be. Master Hub is then pressed (cold work) into one or more Master Dies (negatives). From these Master Dies, Working Hubs are created. If I remember BadThad correctly, the original Lincoln Master Dies lasted through 1915 and new ones created for 1916, to give an idea of scale and usage.</p><p><br /></p><p>Working Hubs were used to press dies. It took two &quot;squeezes&quot; to create a striking-ready die, which is how the 1955DD was able to happen. That, and rather poor downstream QC.[/QUOTE]</p><p><br /></p>
