Good afternoon, Alexander, Thank you for submitting photographs to Mearto for appraisal. Seth Thomas grandfather clocks are fairly common in the marketplace today and generally do not bring very much money. Your clock appears to be made primarily of oak and was made in the second half of the 20th Century. Unfortunately, getting is to run will be almost as expensive as the clock is worth, and having it running will not increase its value. I hope this has been helpful to you. Please let us know if you have additional questions, and thank you again for using Mearto.
