<p>[QUOTE=&quot;IdesOfMarch01, post: 7503264, member: 39084&quot;]It&#039;s my understanding that ancient striking on a hot flan produced flow lines due to the maximum force being applied in the center of the die, with force decreasing radially outward from the center.&nbsp; This causes the hot metal to slightly &quot;flow&quot; toward the edges.</p><p><br /></p><p>In a modern press, the force is applied equally across the entire surface of the flan, thus no flow lines.</p><p><br /></p><p>(Anyone with more specific knowledge and understanding of this process, feel free to add to, or correct, this information.)</p><p><br /></p><p><br /></p><p><br /></p><p>This is outside my area of expertise to knowledgeably answer, but I would speculate that if there are truly no other genuine examples with which to compare a specific coin, one would have to rely on the existence or non-existence of flow lines and possibly metallurgy analysis that would indicate the content and/or age of the coin&#039;s metal.[/QUOTE]</p><p><br /></p>
