Ming & Qing Cash Coins identifier

[JMP]

Years ago, I made this identifier for my own use.
Later I posted it on a Belgian forum, which meanwhile is off screen.
The comments are in Dutch, but the emperors' era names and period of reign are clear:
For Zheng De there is a warning that all pieces are fakes (charms), because there was no coinage during his reign.

One could notice:"Hey, where are the Jurchen coin Abkai Fulingga Han Jiha and the Chinese specimen Tian Ming Tong Bao of Nurhaci (1616-1626), and the Jurchen Sure Han Ni Jiha of Hong Taiji (1627-1643) on this identifier?
Right, those three coin types of the Jurchen conquerors of Ming China got no place on it, as on this identifier the year 1644 shows a clear transition from Ming to Qing.
One is hereby warned .
