<p>[QUOTE=&quot;dougsmit, post: 4509504, member: 19463&quot;]In most cases we find die matches frequently with more scarce coins that used fewer dies in the making of the type while we find few when the coins are very common and were made from a thousand dies.&nbsp; Those of us who specialize in coins from a less common group tend to have quite a few die matches but we don&#039;t always keep double die matches (term: die duplicate) because they don&#039;t convey much information beyond the progress of die wear or failures like cracks.&nbsp; I find more interest in coins hat are die linked, meaning one die that matches and the other that does not.&nbsp; The example I post too often is this set of six coins that share the obverse die but have different reverses.</p><p><img src="http://www.forumancientcoins.com/dougsmith/die03.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p>Some issues, for example the tetradrachms of Syracuse were struck using one die at a time replacing either side as they failed so we get a series that leapfrogs along with each die used with only one or two mates.&nbsp; Some series replaced both dies together.&nbsp; Some randomly assorted dies among several teams working simultaneously.&nbsp; We learn different things by studying these patterns.[/QUOTE]</p><p><br /></p>
