Help with Chinese coin identification please

Please somebody help me to identify coin shown below. I checked everywhere and no idea what it is. Is it Chinese / Hong Kong? And why square in the center is not empty?

Based on the second image it's not a coin. It would be useful if you could find someone who can read that side.

I am pretty sure it is not a coin. On the back is a name of a goldsmith company. The characters are to read from left to right.

Hello

Find this

but not able to read and there is no picture of the reverse

Hope it's help

Hi There,

ahkai is right, that's from a jewllery company (now also a “group” doing lots other business, see https://en.wikipedia.org/wiki/Chow_Tai_Fook).

The Chinese characeters reads right to left (in this case although it's more common from left to right while displays horizontally). 

It reads as a Commemorative token for a big sales. 

Regards,

Ed
