Russia Principality of Tver Anonymous Copper

Without the name of the prince but struck under Michail Borissovitch(1461-1485).

Tver’s foundation year is officially accepted to be 1135, although there is no universal agreement on this date and some estimates place it as late as the second half of the 13th century. According to one hypothesis, the name of the city is of Finnic origin, *Tiheverä. Originally a minor settlement of Novgorodian traders, it passed to the Grand Prince of Vladimir in 1209. In 1246, Alexander Nevsky granted it to his younger brother Yaroslav Yaroslavich (died 1271), from whom a dynasty of local princes descended. Four of them were killed by the Golden Horde and were proclaimed saints by the Russian Orthodox church. (Source Wikipedia)
