A recent listing on Ebay, #1116 1141 2065, involves a 1984 Great Wall silver medal, NGC PF66UC. I do not know how to import pictures of the medal & I do not know how to link the listings to this coin forum. After years of discussion, it is worth looking at the pictures of this medal.
Disclosure. It is not my listing. It is not my medal. I do not know the Ebay seller. I do not even own a silver Type II Great Wall medal. So, I am not trying to help sell this medal. I am just adding to our long term discussion of these medals.
