I question lots of gold I find in Italy; man they will stamp stuff 14K and its plated. However I have found some items that looked pretty old like that and figured it to be plated until I took it home and tested it. Just test it or you will never know for sure. Looks like it found home for years at the bottom of a jetti and just got pounded.
But that just makes it look that much cooler to me.
Great Find,
