Round coin with center square hole to identify - Chinese & So. Asian characters [solved]

Hello,

I am trying to identify the coin in attached photographs, which has been in my posession for about 50 years, I don't remember how I got it.

Diameter: about 14.5mm
composition: unknown, non-magnetic metal
Edge is only a fraction of a millimeter

The center hole, inside a square, still has remains of metal, so I cannot say whether the original whole was actually square.

There are small dots on the field in between the chinese characters, however, not on the other side. Searching with Maktun phone app I get similar images for the non-chinese side only.

Thanks in advance for your kind help, if needed, I can try to get better resolution pics.

This is a souvenir or fengshui token not a real coin, sorry.

These things aren't worth a penny, but nevertheless, they do have a page in Numista:

There are probably hundreds of thousands of them hanging on girls' bracelets 'made in China'.

indeed modern replica of this:


and many replicas do exist!!


your replica is cast, that explains the look of the hole.

Thank you all very much for the clarifications, pictures and links - which I was not able to find on my own for lack of details.

Warm regards
