No clue... maybe find an asian forum, post image there to see who can read the writing... that should get you started... otherwise, take a trip to barnes/noble or borders to check out the world coins guide.
I can help with the identification. 1) Upper left is Jia Qing Tong Bao, bao yuan (Board of Works mint) 2) Upper right is Guang Xu Tong Bao, Guangdong mint 3) Lower left is Kang Xi Tong Bao, bao yuan (Board of Works mint) 4) Lower right is also Kang Xi Tong Bao, Guangdong mint I'm not positive as to the mint of #4 because the image is not quite clear enough.
