can someone tell me what this is ?

Just curious as to what this is

I am guessing it is not a coin but a token or maybe just a good luck charm

Thanx in advance for any information

Yes, most likely either a token or good luck charm (judging by the symbols on the reverse, possibly Korean or Taoist in origin). Certainly not a coin; looks to have been holed at one point; perhaps as a necklace or pendant?

Yes - a charm token from China.
