Just one more thing, that coin is NOT mine, it's elverno's.
Grivna, I am pretty suprised about the early Russian commemorative coins. The more research about them, the more undeniable the link between Russian and the rest of Europe seems to be, in particular Germany.
Gube, who is the amazing mintmaster who engraved some of the best Russian coins actually is German himself! The family ruble as well is linked back to the Bavarian 1828 5 marks. Link:

Btw, here is one image of Pavel I ruble against a Dutch Ducat


The stunning ducat is NOT mine, it's GDJMSP
