Question: is 12 karat gold filled worth anything?
Answer: The term gold fill means that 1/20 of the volume is gold with another 19/20 being some other metal . In this case 1/20 of the volume of the alloy is made up of 12k gold. So to answer your question, yes and no. Yes there's real 12k gold in your piece but no it's not worth much unless you've got a whole lot of it.
