Chinese brass plated game token would be my guess. I can't read the characters so that's the best I can do.
Provide weight, diameter, really anything else besides some pictures and you may get more information. Either way, it's not a coin nor is it worth anything. Therefore it is basically "junk".
A picture of the other side as well as size and weight. Your original picture gives us no idea of scale and only shows one side. I would think it is a token, but given the info at hand, I don’t know.
I tried old google translate and it wouldn't recognize the letters as chinese. That's about all I could do. Good luck!
Get out of here! (and thanks for answering my question on your show a couple episodes ago!) These are not characters of some sort? Someone blowing smoke up my kazoo? LOL
it says 紫禁城 (the Forbidden City).But from the quality and design style, it is definitely not an official museum souvenir
