<p>[QUOTE="RomanTheRussian, post: 186489, member: 7539"]I would love to know what your sources are for this information. It was my understanding from in-depth discussions with people specializing in the series that the edges applied to Portrait 8 Reale coins were made on a two die apparatus. The blanks were squeezed between two parallel flat bar dies. One bar die was mobile (moved with a screw apparatus) while the other was fixed. As the moving die bar traveled along parallel to the fixed die - the blank rolled along between the two dies under very high pressure. This reduced the diameter of the blank to the appropriate 39 mm and it upset the rim slightly to prepare the blank for striking. The edge design was applied to the opposite sides of the coin at the same time. The two die apparatus therefore produced TWO overlaps on exactly opposite sides of the coin and of precisely the same length. One overlap means that the detail was applied with only one die. </p><p><br /></p><p>This series was also struck in an open screw press AFTER they were edged. </p><p><br /></p><p>~Roman[/QUOTE]</p><p><br /></p>
