I received message about that coin from
Manchu legend read from left to right and from top to bottom:"The Imperial Coin of the
Heavenly Mandate", being a counterpart of the Chinese legend above. The Manchu writing
is of the old style, before the improvement made by the dots and rings introduced by
Tai Hai, in 1627.
It is a coin of Qing Dynasty, called "Tian Ming Han Qian".
Before the Qing Dynasty rulers conquered south of the Great wall areas, in
the 44th year of the Wan Li reign of Emperor Shen Zong of Ming Dynasty
(A.D.1616), Nurhachi of Manchu nationality proclaimed himself emperor and
used the imperial title Tian Ming. He minted the Tian Ming Han Qian with
the Manchu inscription.
Nurhachi (1559-1626) is a Manchu khan that in 1616 established Later Qin
 Dynasty. Nurhachi
waged wars with Ming  Empire and was grandfather of
Emperor Shun Zhi who launched the invasion of China in 1644 and became
the first Emperor of Qinq  Dynasty.
