Rare 1928 Chinese Ration Coin (?)

I recently came across about 5 or 6 of these 'China Ration Coins' that the owner had ID'd as being worth $6 quite a while ago. The owner has had some decently valuable coins valued according to him at $6 and I was wondering if any of you could identify the coin for me.

Hi Christian! I can't help with the coin but I will say I enjoy you channel. Glad to see you're a part of Numista!

I don't know what this coin is. The design on it is the ROC emblem though.
