Panda 30 g silver coin - various years

The Chinese silver Panda was first issued in 1983 as 27g coin by the People's Bank of China with a purity of 900.0/1000. This coin was sold until 1985. Replacing the 27g-coin, 1oz and 5oz coins minted in proof quality with a purity of 999.0/1000 were issued from 1987. From 1989 onwards, 1oz coins were also produced as proof like coins.
There are several mints that produced Silver Panda coins over the years, including but not limited to: Shenzhen, Shanghai and Shenyang.
The obverse of the coin shows the Temple of Heaven, the reverse depicts different illustrations of giant pandas.
China issued its first gold coins picturing a panda in sizes of 1/10 oz, 1/4 oz, 1/2 oz, and 1 oz of 999 fine gold. In 1983 the 1/20 oz size was added. There is also a Gold Panda series issued with the same designs as the Silver Panda coins.
2016 begins a new era for Panda coins. The old weight system of troy ounces was replaced by the metric system of gramme, the standard system of weights used in the People’s Republic of China. For the first time the full range of Mint State silver and gold Panda coins will be issued in metric weights of 1 g, 3 g, 8 g, 15 g, 30 g, 150 g and 1 kg.
