Ok I bought a set of coins from Vatican City and they put this coin in the top hole. It is about the size of a US half dollar. I can not find any info on it. All the coin that were in the set were from 1961 or 1962 so I figure it is from one of those year or atleast sometime between Pope Pual XXIII term or what ever you call it. but I beleave from 1958-1962. SO I am not sure if this is a coin or a medal. I am thinking medal. But I am looking for some info on this coin if anyone has any. Also does anyone know its value.
