<p>[QUOTE=&quot;red_spork, post: 4229989, member: 74282&quot;]If you go through Bahrfeldt, Hersh or Crawford&#039;s tables of overstrikes you&#039;ll find something really shocking: there is only a single <a href="https://gallica.bnf.fr/ark:/12148/btv1b10420814m" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://gallica.bnf.fr/ark:/12148/btv1b10420814m" rel="nofollow">uncia-over-sextans overstrike</a> listed from the D&#039;Ailly collection and now in Paris. Crawford later published a second example in CMRR, but even so, you basically never see them.&nbsp; This is quite strange for a handful of reasons, first and foremost that the Crawford 38 semilibral semuncia is an extremely common type, and in theory should have been widely available for overstriking. Second, the Crawford 41/10 Uncia usually weighs 5-8 grams, about the same as the 38/7 semuncia, making it seem like an even better candidate for overstriking. Finally, many 41/9 sextantes are known overstruck on 38/6 unciae, so many that it almost seems like you see as many or more overstruck as on fresh flans. So why so few unciae overstruck on semunciae?</p><p><br /></p><p>If you hoped that I would have an explanation, unfortunately you&#039;ll be disappointed. I&#039;ve got nothing. The Romans struck great numbers of 41/10 unciae so these should be very common. To me this overstrike falls into the category of coins you&#039;d expect to be common, but in practice and even in specialized overstrike collections, you almost never see it. I have no idea why, but I was very happy when I finally managed to decode the undertype of this uncia that a friend pointed out to me. It took me a bit to get it, but if you look in front of the obverse chin you can see Mercury&#039;s petasos. On the reverse you can see a&nbsp; trace of the undertype prow&#039;s rostrum tridens poking out at the top left of the overstruck prow. The devices, style, module size and weight leave only a single possibility for the undertype: the 38/7 semuncia. I&#039;ll attach a photo at the end that will help you see it better if you can&#039;t spot of from the photo of the coin alone.</p><p>[ATTACH=full]1081954[/ATTACH]</p><p>Roman republic Æ Uncia(6.06g, 22mm, 10h), anonymous &quot;post-semilibral&quot; series. 215-212 BC.
