Sorry for the mistake in the previous post - I do not know much on the English language!
Dear colleagues! Everyone - thank you very much for your answers and opinions and hypotheses. I have, for many years engaged in the study of minting coins Gireys-Crimea, Golden Horde coins Kaffa. I submitted this photo coins differ from those issues, which are usually minted Kaffe.V particular, on these coins present flag, coat of arms is very similar to the Duke of
Milan. It is not usual for Kaffa rider - usually copper coins Kaffa depicts St. George - as in tune with the Bank of Saint George. On the same coin, we see a different interpretation of the rider. I believe that before you make a final decision on the
membership of these coins the Genoese colony of Kaffa, we must eliminate all other options - is it possible that this coin was minted somewhere in Europe?
