Here is the 2018 Beijing Expo Panda. There are several varieties (brass, copper, silver plated). Apparently these will be sold at the Beijing Expo in November. The mintage is 300 for silver proof (and the other variations) and 100 for silver antique. You can find them on eBay and Luckpawnshop.com. Here is one for a good price, IMHO. https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com/ulk/itm/253894574438
Here is another seller, who is offering good prices for these Beijing expo pieces. https://www.ebay.com/itm/253894738218
