I bought the coin in the Russian online auction www.molotok.ru. The seller also sell coins of the Baltic States 15-17 centuries.
Weight is 1.70 g.

Yes, I have seen examples of these coins, but we can not expect them to be completely identical.
It's possible - coinage of the period on an uneven circle?

What we can say about the authenticity of this coin?
