I think these are tokens. Chinese and Italian respectively, but I'm not sure what they're for since there is no monetary units or dates....also they are both the same on the reverse. I couldn't find this one anywhere the dragon was different than all the other coins I searched.
The ruler depicted on the italian coin is Vittorio Emanuele III. Are you sure the reverse is the same as the obverse? Also some measurements would help.
If the reverse is NOT the same as the obverse then it is either nickel or stainless steel 20 centesimi. It should also be magnetic. Nickel was produced 1936-1938 and steel was 1939-1943.
Traditional Chinese holed coinage have square holes. Circular holes are traditional with Japanese coins and so I'm guessing that's where its from. The Dragon coin I can't say much about. Most old Chinese coins depict a dragon coiled like that however I have never seen a wreath on the reverse. i.e. you may be dealing with fakes.
The reverse is the same, thats why I don't think its a coin. Its 20 MM. It is also not magnetic, The first asian coin I think is a bus or train token, the picture does not give it justice it is basically a washer with characters on it. As far as the Dragon coin I have seen similar wreaths on coins from a few different asian countries but not that particular dragon. It may be a fake...still curious though.
The inscription reads bu ke si yi which translates as "inconceivable" or "unimaginable". The "token" is certainly not old and since the inscription is written in "traditional" Chinese characters, as opposed to "simplified" Chinese characters, it most probably did not originate from mainland China. That means it could have come from Japan, Korea, Hong Kong, Singapore or any of the overseas Chinese communities such as those in the U.S. and other countries. Gary
