There are three pin marks on the back, a characteristic seen in items from 19th-century Britain and France, so I believe this item is from that era as well. The size suggests it's a cake plate. It's difficult to see in the images, but there are scratches and stains commensurate with its age, so please be aware of this. Diameter: Approximately 18.8cm Height: Approximately 1.8cm Sizes are approximate. The actual item may differ slightly in color from the images.
