I need help. [решено]

  I have this coin, but I have no idea what it could be. 

  I would say it is from China, but other empires have also made coins like this. 

  There was an attempt to purge the last owner. 

  Have 15 milimiters.

  In addition to helping me find out what coin this is (if it is not a token), can you tell me if it is real? It seems like it to me. 

  If it is real, what is its value?

                                    Thanks.

It is for Guangxu era but seems to be a tin copy, even if real worth very little in this shape
