Unknown Chinese coin

I have this very worn ancient Chinese coin, and I was wondering if any of y’all could tell me what it is.

 The weight is 3.5 grams, and it’s 24mm.

It's one of these.

 Do you know which one?

Not enough details to even make a guess. Maybe pictures outside the flip would help.

Magnetic?

Slightly.

Sorry, but I don't know. It's too worn.

No problem!

Personal interpretation, but I see the older chinese character for 4 on the reverse.

If you want an ID, you'll need to post clear, non-blurry images for the forum members to look at. Not to be rude, but the provided images are completely indecipherable at this moment

Could be Korean…

It’s not super blurry, it’s just very very worn and  indecipherable.

Click on any of the images you posted, they are extremely blurry. 

I concur that Korean (Joseon) seems likely due to what could be furnace numbers on the coin, but the quality of the images will not allow a better look.
