Ouch and what a shame! But to be honest, I would be very happy to even obtain a damaged example as genuine examples are just not affordable.
I think it's genuine as well. Mind you, up till ten years ago, Chinese coins were viewed as junk and many silver coins were sold at scrap metal. It's only very very recent where Chinese coin prices exploded. I started at the very beginning of the boom and got very very very lucky.
