Been hunting these overstruck coins for a while and these can be quite uncommon to really scarce. While overstruck coins may look ugly, some are really worth a fair amount. Here is a spoiler: http://www.gxseries.com/numis/rus_imperial/overstrike/rus_overstruck.htm
I think it's a two kopek coin of Elisabeth I the Empress (1741-1761). This coin was overstrucked during the reign of Catherine II the Great (1762-1796).
Looks like I didn't make myself clear in the first place. The showcase of my Russian overstruck coins can be seen here: http://www.gxseries.com/numis/rus_imperial/overstrike/rus_overstruck.htm
