This is some kind of imitation of Byzantine Class C folles. --Except, the diameter is around 14 millemeters! For comparison, here's an example of the ostensible prototype, associated (let's say) with the reign of Michael IV (1034-1041). This is around 24 mm (sorry, no scales). Back to the iffy one, I dimly remembered seeing examples like it on Italian ebay. But that was most of the traction I was getting. The American dealer who it came from referred me to a closed listing in Forvm Ancient Coins. That was some help, but mainly by way of references to which I had no access. More specifically, too recent to find online. From there, I went back to two places. The one published reference I have (Andrea /Contreras, The Norman Coins of the Kingdom of Sicily (2015), lists one anonymous issue of similarly neo-Byzantine folles (28a and 28b). From there, a citation of a particular reference, Travaini (1995) caught my eye. And from that point, I went back to the listings on Italian ebay (some current), and found citations of something later by the same author. Thanks to Google Translate (only useless when you're trying to compose), it emerged that there were were indeed Norman imitations of Byzantine folles, apparently from Calabria, from the earlier phases of occupation --one range thrown around was c. 1060-1080. More specifically, that very reduced modules were involved, and that, apparently even as such, the frank imitations, however appallingly crude (evoking 11th-earlier 12th c. deniers from Normandy proper), consistently predate both the imitations of later prototypes, and subsequent issues. ...Well, that's what I'm hoping. Anyone's input would be cordially appreciated.
