Dear Carol,

Thank you for the additional image. This is a porcelain collector plate made by the German manufacturer Gloria in Bayreuth. The plate itself is decorated with a scenes of a couple after the French artist Antoine Watteau. This decor is printed and not painted with hand. Also, we have golden decor with 22-carat gold. This plate was made for the export between 1960-1979.
An estimation would be between 10 to 20 USD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With best regards,
Georg
