Kolekcionavimo forumas - monetos, banknotai, pašto ženklai ir kt.

I was recently given this note in exchange for some work I did for a friend. I know nothing about these ans if anyone can
help me understand what it is it would be much appreciated.

Russian 500 rubles 1912, nothing special, cheap banknotes in this state.

Thanks
