Value of Black Forest Grandfather Clock?

Original "DOLD EXQUISIT" Grandfather Clock purchased used. What can you tell me about this original Heirloom timepiece from the BLACK FOREST? Period of manufacture (suspect 90's, but unsure), and average resell value (price range) for insurance purpose. A beautiful clock in operational condition and only minor cosmetic damage due to age. Top center glass can easily be reinstalled or repaired back to near original condition. Last service date 8/14/2023. Any information about this timepiece would be appreciated. Thanks in advance.
