I ran across this 4" medallion with a Spanish 8 Reales reverse and I'm not sure of the obverse because of the glue someone applied to it. It seems to be bronze and that is about all I know about it.
I can't seem to find any information on it anywhere and I was wondering if anybody here might be able to shine some light on it. Could it be some kind of a tourist token or an emblem used for decoration of some kind? With it being 4 inches (100mm) wide I guess it could be anything. Do you think there is any value to this piece?
