The long-standing panda series is one of the world's most popular. Different from many other silver series, these coins carry a fresh design annually. The 2021 engraving features an adorable scene of a panda cub and its mother. In 2016 this series transitioned to the metric system. Now each Brilliant Uncirculated 10 yuan coin weighs 30 grams and contains .9645 troy ounces of investment-grade .999 fine silver.
