Thank you for submitting your items for appraisal. These appear to be late 19th century japanese small dishes, also known as mamezara 豆皿 plates. They are used for serving small pieces of different food at at japanese dinner. It is a different concept of eating. By placing the food on tiny plates you pay more attention to each bite. The plates in your possession were produced for daily use in Japan, not for export. The estimate is for the set of five, based on simlar offered or sold at auction.
