I have some 'old' Chinese coins i could do with some help on. I was given these when I was in Xinjiang by an old guy who I helped with his car.
I want to see if anyone can give me some guidance on even where to start?


So, we have:
Top Left: 3.47g 24.5mm (Thickness - 1.25mm)
Top Right: 4.17g 25.4mm (Thickness - 1.23mm)
Bottom: 3.05g 24.85mm (Thicness 0.95mm)
None of them are perfectly round and none have the same thickness around the coin either so that is at the widest point.
Two seem to be a cast bronze and the bottom one looks more copperry (yes, that's a word!), although still cast.
Some of the centres have small holes from wear and poor casting?
Let me know if anyone wants anymore info. As with any 'old' coins, I haven't ruled out them being modern reproductions!
Thanks in advance :)
Dan
