Here's a link to a picture of a strange medallion found, in of all places, inside a fish in Canada. Only thing stranger - my brother found one just like it the other day on the ground. Any ideas? It's the size of a silver dollar and the reverse has the same symbols around the edge but two different ones in the middle. All four middle symbols are represented among the 8 around the edge.
