Certificates

Many valuable instruments come with certificates of authenticity. Usually, they contain the following information: the owner of the instrument, the name of the manufacturer, a short description of the instrument with photographs and measurements, and an official signature. By providing an official signature, the exhibitor guarantees that to the best of his knowledge, the instrument was manufactured by the respective master. Frequently, the certificate also contains additional information about the date of manufacture and the state of preservation. The certificate does not include a value appraisal, as the commercial value may be subject to extensive fluctuation. If so required, for example for insurance purposes, the fair value of the instrument may be established in a separate valuation report.
