The Qing Dynasty, also known as the Manchu Dynasty, was the last ruling dynasty of China, ruling from 1644 to 1912 . It was preceded by the Ming Dynasty and followed by the Republic of China. The dynasty was founded by the Manchu clan Aisin Gioro in what is today northeast China (also known as Manchuria). Starting in 1644 it expanded into China proper and its surrounding territories, establishing the Empire of the Great Qing. Complete pacification of China was accomplished around 1683 under the Kangxi Emperor.This coin is unconditionally guaranteed to be authentic
