anyone knows anything about this coin and what is worth? i found it 20 years ago when i was swimming in a river in Croatia. back of coin: ein kreutzer 1701 k front:M.THERES D G RIGHBA RAAUST
That would be 1761 K. The obverse is Maria Theresa Empress of Austria from 1740 -1780. The `K' denotes that it was minted at Kremnitz mint in Hungary. There were 22,923,000 minted there for that year so it is no particular rarity. many examples survive. sadly, in that condition it's value to a collector is no more than a couple of dollars. Ian
