<p>[QUOTE=&quot;medoraman, post: 1316863, member: 26302&quot;]Actually sir I believe the majority opinion on center pivots is that they were used to round and weight a flan before striking. There is amply evidence upon microscopic examination that the center pivot is compressed by the striking. There are even issues with these pivots in every state of view depending on the strike. Under the design is also sometimes found surface striations in a circular motion.</p><p><br /></p><p>For others, this method of manufacture started on the large bronzes of Ptolemaic Egypt, but continued through the Roman provincial coins in the east through the 3rd century. It was quite widespread, but not completely understood why.</p><p><br /></p><p>Chris[/QUOTE]</p><p><br /></p>
