I was wondering, when does a non fiat panda become a "Official panda issue" and not just a "Official mint medal"? For example the 2016 Nanjing panda( from Lucky) is named a official mint medal and not a official panda issue on the NGC slab, but the 2016 Tempel panda (also from the Nanjing mint) is named a Official panda issue. To make it even more complicated, the 2015 Nanjing panda (from Lucky) did get the "official panda issue" designation on the slab. For the 2014 panda I do see different slabs, one with the panda issue and the other just a mint medal. Two days ago I did receive the 3th panda book from Peter, and I found out that the Nanjing panda's (2014 till 2016) are not in the book. Meanwhile the 2016 Tempel panda did get a full page and a panda number. Then the Trigo panda's from the KL money show, the are not from an official mint. Still the are a official coin show panda, so why did the not get a Official panda issue designation? For the future, is it important to panda collectors that a non fiat panda does get an "official panda issue" designation on the slab?
