Ancient coin "800 Indonesian Bali ..boo yun .qyng dyn
Welcome to the site! I'm replying just to bump your post in the hope that someone with the right expertise will help you. Since it is Boo Yun isn't it Chinese rather than Indonesian? .
Hello, it's an Indonesian cash imitation made for local circulation. Reverse is a copy of a Manchu mintmark from a Chinese Ch'ing (Qing) dynasty coin. Regarding the date, it can be no earlier than the late 1600's and may be as late as the late 1800's. The metal seems to be brass with zinc content. There's a book about coins similar to your one, entitled "Recherches sur les monnaies des indigènes de l'archipel Indien et de la peninsule malaie" By H.C. Millies (1871), you can find it (legally downloadable) here: http://books.google.com/books?id=p0QvAAAAMAAJ&printsec=titlepage&dq=inauthor:h.+c.+inauthor:millies&as_brr=0
You can find plates at the end.
