I am interested in finding out more about my silverware set. It was purchased in 1972 in France. The certificate reads, “The Regency, Ensemble D’Orfevrerie, a Supercharge D’Argent Fin”. I have been unable to match the set/design with any online. My guess is it is silver plate as the back of the pieces reads, Oneida Silversmiths plate Made in UK. Anyone know the history of this set? What might it be worth? Or where to get a fair appraisal? I can email you pictures, attachments on this site are quite limited.
