How do I date a Seth Thomas mantel clock?
1 Answer

To date a Seth Thomas mantel clock, examine the gears inside. If the movement is wood, the production date of the clock is somewhere between 1817 and 1830. Clocks made after 1881 may feature an ink code date stamp on the case back or bottom. A licensed appraiser can provide assistance with determining the exact manufacturing year.
