SNG Copenhagen 784 ( same dies ). An extraor­dinary piece, especially with remains of its original silver plating. Some marks from cleaning, otherwise , about ex­tremely fine. During the Empire many Greek cities in the eastern Mediterra­nean area produced very large sized bronze coins. Commonly termed ‘medallions’ in numismatic literature, they should, in fact, be seen as commemorative high denomination circulating coins. The concept of a monetiform medal only began in the Re­maissance, when artists, using Roman sestertii and other large-sized ancient coins as their models, began making them. As can clearly be seen from Roman precious metal ‘medallions’, the an­cient versions, like the over-sized Imperial bronzes that were minted in Rome and were particularly common during the 2nd century, all had some sort of understood monetary value. Gold and silver pieces were actually multiples of normal denomina­tions - this must have been the case for aes as well (you could have bimetallic pieces that would have been double sestertii or more). We can be certain of this because while some bronze were clearly kept as keepsakes, others must have circulated since they turn up in hoards containing all manner of smaller coins. This is even clearer with the many large-sized AE issued by the Greek cities in the eastern provinces of the Roman Empire. Since only a very few mints were allowed to strike silver coins, and those only for regional use such as the cistophori of Asia Minor or the various types from Caesarea in Cappadocia, the proud cities of Asia had to turn to the issuance of exceptionally large and heavy bronze coins when they wanted to celebrate a special event. These coins would have been the equivalent of quinarii and de­narii, among others, and would have been easily recognized by their exceptional size (far bigger than contemporary sestertii for example). The fact that this piece was given a silver plating when it was made emphasizes its special nature and high denomina­tion.
