🕰️ Antique Clock Identification & Value
Antique American clocks (Seth Thomas, Ansonia, Ingraham, Gilbert, New Haven, Waterbury) were mass-produced, so most mantel and shelf clocks are affordable — the value comes from maker, case style, movement type and working condition. Rarer forms (banjo, grandfather/tall-case, calendar and fine German makers like Gustav Becker) reach higher. A running movement, original dial and undamaged case matter most. This guide identifies makers and movement types and gives hedged value ranges from sold prices — an educational estimate, not a formal appraisal.

Frequently asked
How do I identify my antique clock?
Look for the maker's label or stamp inside the case or on the movement, then the case style (mantel, shelf, banjo, tall-case) and movement type. Many American makers pasted a paper label inside the back door listing the company and model.
Does it need to run to have value?
A clean, original, running clock is worth more, but a non-running clock of a good maker still sells — movements are often repairable. Condition of the case, dial and completeness usually matter more than a stopped movement.
