Thank you for submitting your items for appraisal. These appear to be two chinese porcelain plates in the tradition of Canton export porcelain, having transfer printed outlines with additonal hand painting in enamel colours. Small chip and hairline crack at the rim. A four character Qianlong Nian Zhi mark at the underside, but most likely dating to the republic period, early 20th century. The estimate is based on similar items offered or sold at auction. There is no measurement for the sentimental value you might attach to the item.
