I really know nothing about these, but Russian
orthography a little. The letter on the
obverse seems to be "W", copying the Greek Omega, here a fancy "O". The line at the top of the
reverse inscription indicates an abbreviation, here KNZb for KNJAZ', "Prince" (from the
Gothic "kuningaz", or whatever it was, cognate to
King in English), with the letter
types following
Church Slavic, "b" being the letter "jer'," at this late date merely a sign of palatalization of the preceeding consonant and transliterated into the Latin
alphabet as '. The second line here is not "velikii," (definite adjective "the great"), but "velik"(indefinite adjective), whether due to space constraints, or grammatical mistake I don't know, but my impression is that these almost always have the definite form of the adjective. Come to think of it, it is odd that the word Knjaz', ends in a jer' (the "soft sign"), while IVAN does not: it should have the letter jer (the "hard sign" which was abolished in the
orthographic reforms after the Revolution). This would be very, very suspicious in a MS, but on a coin??
By the way, what Ivan is this supposed to be (I think there were at least four)? The use of a horseman instead of St. George may indicate that this is not a Muscovite coin
per se, but a coin of another authority (e.g., Tver').
And, yes, I have heard that these are frequently faked (the reason I don't have any of these otherwise interesting coins). I
hope this helps more than confuses, George Spradling
