VINTAGE Mexican Silver Brooch Very Old

This is one of the older Mexican Brooch I have ever seen. I left it to you to clean it as you want, but many Mexican Silver Experts prefer to retain the old finish. The brooch is 2 inches round. I has a couple of little bumps on the petals. (it only adds to its charm.) There Is a mark on the back of the brooch it says Sterling and RAG and Mexico. The RAG is in the book but not a name. A nice older Mexican Silver Brooch. For you from Kansas!
