mfm said:"There is for example one youtube clip of one guy buying silver pandas in Shanghai and the shop tell him they don't buy back silver pandas, only gold pandas."
This is a very different comment from your first one of "Actually its common for shops in China not to buy back silver pandas because of the massive counterfeiting."
All dealers aren't expected to buy back silver coins, and it may have nothing to do with 'counterfeiting' - but rather, they just don't buy silver.
