Another copy preserved at the Münzkabinett der Staatlichen Museen of Berlin, link to the page of their website showing the photo of the coin: http://www.smb-digital.de/eMuseumPlus?service=ExternalInterface&module=collection&objectId=2440382&viewType=detailView.

The cgb copy pictured here does not have the same dies as the Berlin copy. One can wonder if the globule on the reverse is present, I believe that the probability that it is off-blank is high enough to justify its presence in the description. This coin and that of Berlin are therefore very probably of the same type.
