But you never told me what I should do with them . . . . . At least they're not brass . . . . Did you show them to Marites?
You can either save them as conversation pieces, or sell them to a jeweler for whatever they will give you. It's unknown the silver content, so you will have to find someone reputable. I say keep them. You have a good story and memories to boot. I would think they are too heavy for the Christmas tree, but that is another option.
Sandwiched not plated. Like our current dimes, quarters and Kennedy halves. Just made with a silver mix from 65-70
You know, I just KNEW you would come up with a useful function for those . . . . . . I'll be the envy of every half cousin / brother / sister / kinfolk in Georgia . . . . . ! Z
