Thanks Lech for bringing this to a wider audience. The Göttingen example is, from what I can see, probably a normal bronze coin, perhaps with later
silvering. I checked it against my database (with 52
officina B examples of
RIC 35), but found no die matches. Perhaps not surprising considering the enormous production of dafne coins.
By the way, I will give a presentation at the Warszaw conference on Constantinian
forgeries.
