After casting about on the internet, I think this is a Russian Denga of 1732. I wonder if a Russian collector could comment on whether this is likely a "dug" example or simply how these pieces come when circulated.
I`m not Russian but I have had many of these coins pass through my hands over the years Denga or ½ Kopek, Crowned double headed eagle , Reverse; date and value in cartouche. Strange that 1732 is not listed in Krause 1701-1800.
It could be 1732 but maybe 1731 - it's a lot more common. A nicer looking denga would look like this:
Yes it is definitely a dug example as indicated by the corrosion over the entire surface of the coin.
