Цитата: "Idolenz"The pros and cons of Chinese cash coins you have always something to do. You thought you identified it ... think again. 
At least Chinese had different writing on. Japanese Kanei mon you are lucky if you have a mark on the reverse or a different metal
anything else is detective work.
Depends, dynasties from before the Qing don't have the Manchu mintmarks, and had only the occasional reverse character or stroke variant to differentiate them.
And I have Chinese Cash that I've owned for a whole calendar year now, without exact type ID yet.
