Hi Ronald,

Thank you for contacting Mearto with your appraisal inquiry.

Seth Thomas was one of the most important figures in the history of American clockmaking. In 1813 he founded what became the Seth Thomas Clock Company in Connecticut, helping transform clock production from small craft workshops into large-scale factory manufacturing.

His company produced millions of affordable shelf, mantel, wall, and regulator clocks during the 19th century, making reliable timekeeping widely accessible in American homes. Today, Seth Thomas clocks are significant because they represent the industrialization of clockmaking in the United States.

This is an "Ogee Mantel Clock," which were unusual because their cases used a distinctive double-curved “ogee” molding on the front frame, creating an elegant S-shaped profile rather than a flat rectangular façade. Another unusual feature was the reverse-painted (églomisé) glass tablets in the door, often decorated with gold stenciling, columns, or scenic designs.

Seth Thomas, along with other makers such as Eli Terry & Sons, and the Ansonia Clock Company, made them, mainly between about 1840 and 1860. These clocks represent the mass-produced yet decorative American shelf clocks that became common in mid-19th-century homes.

Elihu Geer was a 19th-century clock dealer and retailer, best known for selling American shelf clocks during the early industrial period of clockmaking. He operated in Hartford in the 1830s–1850s, during the time when Connecticut was the center of the American clock industry. Rather than manufacturing most clocks himself, he typically retail-sold clocks made by major Connecticut makers but sometimes labeled the clocks with his own name. In the 19th century it was common for local merchants to place their own printed label inside a clock case, even though the clock movement and case were manufactured elsewhere. This helped promote the retailer and establish trust with buyers.

Other Seth Thomas Ogee Mantel clocks can vary broadly, and those with elaborate dials, gilt columns or reverse-painted doors tend to bring more money that clocks such as yours, which have a more restrained decorative program.

Looking at recent auction records for similar Seth Thomas Ogee Mantel clocks, if you were to sell this at auction you would likely realize between $75-125. It's worth noting that a clock dealer might pay more than that for one if it's in good working condition.
