Is this a coin?

Is this a coin? If so, what is the date, mint and what country is it from? If not a coin, what is it? Any information on this possible coin would be greatly appreciated! It is the size of a half dollar. Non-magnetic. And Thanks in advance!

Not a coin, no. It's a "Chinese Charm", though could just as easily be Korean or Japanese.
