Chinese coin [επιλυμένο]

Hello
I got this Chinese coin but I am not able to identify it. Could someone help me out? The coin is 29 mm and it weights 5.8 gr.

Thanks

This is the closest I found

Hello,

I'm more of an expert on Qing dynasty coins, but I think this coin matches up the most with yours:

The characters (建炎通寶) look most alike, and Chinese cashes' diameter can be highly irregular, with types differring by as much as a few mm.

I agree. Definitely Chinese 1127, worth about $20. Not the easiest to get!

Thank you all!!
