Chinese coin to identify

Hello everybody, could someone help me in identify this coin? Weight about 3 grams, diameter 24 mm.
Thanks in advance!

The characters seem to be 雍正 (Boo-je). I cannot find a coin from that era with the specifications you've mentioned though. You can use this site as a reference.

I think it is not Chinese cash coin at all, those characters on obverse does not look familiar.

The characters on the obverse are written using the traditional Mongolian script. It is likely a coin from the Qing dynasty.

Thanks to everybody! Someone could tell me if the coin could be worth something?

I believe it is this one, or at least similar.

I am not an expert in Chinese cash coins though.
Usually, they are not expensive because of the very high mintage numbers. My estimate in that condition, $3-5.

Though I checked on eBay, and they are sold for more. But keep in mind it also depends on scripts, maybe some other features as well.
