If you don't know the history of them, it might seem a couple of "common" Russian coins. First up is the illusionary 1795 MM 2 kopek that I have been hunting for more than a few years. Sure it looks like a common 2 kopek coin but there's a history to this. In 1795, Moscow mint was reopened this year to overstrike coins since 1789. But this is no ordinary coin to start out with. Not only did they overstrike old coins that were no longer suited to the population, they also overstruck Sadagura coinage that were struck in Turkish gun cannon! If you have no idea what this is, this is what it would have looked like originally: As far as I know, there's probably less than 20 known but it's clearly scarce. Next one here is equally tough. Struck with the same material, it's a 1771 Sadagura PATTERN coin, 3 dengi. Pretty neat and tough coin to find.
The coin 2 para / 3 kopeks was minted for circulation in Moldavia & Valachia (Romania) in 1771 by baron von Gartenberg for an order of Russian Empress Catherine the Great.
I don't think that's true Siberian Man. The 2para-3dengi was only struck in 1772 to 1774 and 1771 coins are generally considered as either scarce or pattern.
Baron von Gartenberg got an order to make the coins in February or March 1771. And I think that he started the mintage not in spring of 1771. Maybe, first coins appears a several months after. As I know, baron von Gartenberg was not the only mint master for Moldavia and Valachia: another mint masters was general-major Melissino and premier-major Popanelopulo.
