Where are Silver Pandas Minted?

By GovMint :

Chinese Silver Panda coins are struck in China at multiple mints, including Shenzhen (Guobao), Shanghai, and Shenyang. However, Chinese Pandas do not feature mint marks to indicate their origin, with the exception  of 1987 Pandas. This lack of mint marks makes it challenging to determine each coin's exact mint of origin by simply looking at it.  Some dealers like GovMint can sell certified mint-identified Chinese Silver Panda coins despite the lack of mint marks.
