There are not a lot of Russia coin experts near me. These are some pieces in my possession and don't know for sure if they are genuine. I welcome any opinions. If I posted this in the wrong forum, please pardon me. First coin is Tannu Tuva 1934 20 Kopeks Second is Khorezm People's Republic 20 Rubles. Can't make out the date Third is Moldovia and Wallachia 1772 3 Dengi Last one is Siberia 1771 Kopek
