Unknown Chinese coin

Could someone help me identify this Chinese coin?  If possible, please post a link to the coin in the Numista catalog.

hello it's not from China but Korea I think, the 1st photo is to be rotated 180 degrees, it looks like this one, I'm not 100% sure

N#37238

 

Hello

You were more reactive than me

Agree with you

Looks right.  Thank you.

Sorry

After looking on my computer and not on my phone

it seems that there is a dot on the left caracter so not the good one

can you please add the weight and diameter

Like the coin 36 in this link

https://en.wikipedia.org/wiki/Korean_mun

And maybe a dot on the right too 

But i don't have any books of Korean coinage  

So i can't help you more 

You could try to contact the Korean referee to have more information and add it to Numista 

 Edit still don't know my left and right😁
