Zhi Dao Yuan Bao China [решено]

Hello everyone

I have this currency that I cannot clearly identify (not much documentation on Vietnam currencies)
Maybe a Chi Nguyen thong bao or Chi Dao nguyen bao
3.74 gr
24 mm
seems to be tin


From what I could find it is an imitation of a Song
but the link that I found on Numista does not match with Malaysia coin
https://en.numista.com/catalogue/index.php?r=chi%20dao&ct=coin
(difference in weight and diameter but also in quality with the edge made with care on both sides of the coin)
Did not manage to find more information or pics on the web


Thanks for your help
Guillaume

The metal looks like bronze (tin is generally much lighter in color). The writing looks like this Vietnamese Chi Dao Nguyen Bao (which you suspected) in Zeno.

Hello Jane6301

I believe you are absolutely right
left shoulder on the Yuan
Didn't see that......................................
I have this coin in a Vietnam lot which led me to look on the trail of Vietnamese
Thank you for correcting my mistake
