Looks like someone took the gold off of gold filled or gold electro plate?
Ill know more about the stuff when I get them in hand with some tools to test.
Could be just a collection of costume jewelry that has been well used....Cheers, RickO
What ricko said.
gold filled has value, gold plated not. Somebody's experiment?
Yup, seen that junk jewelry type stuff before. No mystery IMO. Peace Roy
