<p>[QUOTE=&quot;Silverlock, post: 3249068, member: 98181&quot;]I just received a Ptolemy II tetradrachm with a feature I&#039;ve seen before and long wondered about: the reverse is concave (bowed in), and the obverse convex (bowed out). This isn&#039;t post-strike damage or metal flowing around the edges of a die. The entire surface is evenly bowed. The strike appears to be even, so it isn&#039;t a matter of the reverse die being worn on the edges or anything. The only thing I can think of is the celator actually engraved the reverse into a curved die. That would seem to be very difficult to do, and I wonder why they would bother. Any thoughts?</p><p><br /></p><p>[ATTACH=full]852149[/ATTACH][/QUOTE]</p><p><br /></p>
