In 1980 we had this set appraised at a local Jewelry shop and their appraisal was over several thousand dollars, how could there be such a discrepancy? could they have mistaken it for solid silver?
for these OKA sets are the majority of them silver plated or are they all silver plated, other than content testing is there another way to determine what kind of set we have?
Who can do the content testing? a jeweler?
