For those who do not know, two online coin galleries are frequented by Chinese precious metal coin collectors/investors. These are handy tools, both offering pictures, weight and mintage.
1. jibi.net -Google Translate does a good job on it.
Dingxin gallery. I like it better because its interface is not so
cluttered and it offers better filtering. But it is in Chinese only.
Goolge Translate does not work on the site. I have translated the
headings and dropdowns for easy reference.
