5th unknown Asian coin

If you can identify this one you are really good  
Weight 4.55 grams, diameter 25 mm.
Brightness increased a little, and the coin I don't know if I rotated it correctly.


Thank you

I enjoy verifying your Asian coins. Thanks for the fun.

Korean mun. The top character 帝 (right on your coin if you rotate it 270 degrees) is a good indicator of Korean coinage. However, the characters are very worn so I cannot guarantee that this coin is Korean. But, the reverse shows characters too, which is common of Korean coins regarding values and "series numbers."

Maybe if you rinsed the coin in hot water, I could identify the coin even further for you.

I love them too, they go straight to my collection
I already tried to clean them a little with water.
This is the best it goes I think.
 
So there aren't more chances of identifying?

Little to none.

Plus I'm at basic level regarding Korean coins (not that it has to do with me being Japanese   ).

Hmm that's very sad, I only collect them if I know what exact coin it is.

Sell it on eBay. Maybe I might like to trade it for something, although it's barely identifyable.

Hmm I'll wait a little longer, and after that I might trade/sell it.

Okay, that's good.

In the meantime, upload more coins for me to identify. It's 2 in the morning, I'm reading The Great Gatsby for English, and I'm in the mood of helping others out.

Sure, in a few minutes
