<p>[QUOTE=&quot;medoraman, post: 1148264, member: 26302&quot;]I hear what you are saying Gao, but just looking at Frank Robinson&#039;s current auction lot 420 is a brinze of Justinian double struck with the design offset by a good degree. It looks similar to the pic Doug posted you referred to. This is on a heavy coin, which this minted said was easier to strike, and less prone to double strikes than thin ones.</p><p><br /></p><p>You may very well be right about some being minted an &quot;original&quot; was with curved dies, and others flat and punched later. I just have went back through gold, billon, and copper examples, and have seen flat marks in the very center of the concave that should have been well struck, if any part of the coin would have been. These are vf/ef coins, and the &quot;punch mark&quot; is fairly common.</p><p><br /></p><p>I don&#039;t know of course, just thought it was excellent information for discussion.[/QUOTE]</p><p><br /></p>
