Hi Folks

Please can you assist in confirming the identification of these coins as https://en.numista.com/catalogue/pieces17924.html and help identify the date. All are roughly 25mm in diameter and were part of a purchased job lot on ebay.

Hey dude!

Identifying these is a serious chore, it took me ages to identify the single one that I have, so let me link you to an identification guide by David Hartill. https://pdfcoffee.com/qdownload/david-hartill-cast-chinese-coins-trafford-publishing-2005-pdf-free.html

The smallest differences in the symbols can be very significant, even if it's the same text. Different fonts can mean entirely different minting periods and locations, so good luck & happy hunting!

Thanks very much for the link. Very useful!

Hi,
only coins number 1 & 2 are from Yunnan Province (the link you gave)

Number 3 and 4 are from Beijing (Boo-Yuwan):
