Thank you for submitting your item for appraisal. This appears to be a japanese light celadon glaze porcelain vase of the 1960s or later, shape inspired by chinese Ming dynasty vases. The photo of the characters at the bottom is to blurred to be able to read the characters. The estimate is based on similar sold at auction. There is no measurement for the sentimental value you might attach to the item. If possible add a better photo of the signature.
