What are they made off? I am not sure. Weight 18,1 gram and it states 999/1000 silver on almost all medals. Each medal is ca. 38 mm, about same size as silver dollar, see picture 6.
BUT IS IT REALLY SILVER??? I lowered to price to sell as rare collector items.
There is also room for a certificate, which is missing.
RARE MUST-HAVE COLLECTORS ITEM!!!
