This article is within the scope of WikiProject Numismatics, a collaborative effort to improve the coverage of Numismatics articles on Wikipedia. If you would like to participate, please visit the project page, where you can join the discussion and see a list of open tasks.
Notice: I have received from Y.K. Leung the following message. Some text and images were copied (by someone who did not request permission) from his Chinese numismatics web site  to pataca. His message, granting permission, is shown in this file. My original request to him is quoted in his reply. Regards, Robert Dodier (Wile E. Heresiarch 15:53, 27 May 2004 (UTC))
