Most antique and old clocks found in family homes are worth approximately $50-200, and a large share of them were mass produced in Connecticut or Germany between about 1880 and 1950. That covers the black mantel clocks, the oak kitchen clocks, the wooden tambour clocks on grandparents' shelves, the souvenir cuckoo clocks and the brass anniversary clocks under glass domes. The clocks that bring real money are a smaller group: early American shelf and tall case clocks, good French carriage clocks, Vienna regulators in fine cases, and pieces by makers with a strong following, especially when the original movement, dial and finish are all still there. What decides the price is the maker, the type of case, whether the movement is original and whether it runs, in roughly that order.
Reading a clock takes a few minutes and a flashlight. Almost every useful clue sits on the back of the movement, behind the dial or on a paper label inside the case, not on the front.
Quick answer
- Most old mantel, kitchen and cuckoo clocks sell for $50-200, running or not.
- Open the back: the maker's name, trademark and country stamped on the movement plate tell you most of what you need.
- The big money is in early, original, hand-made or high-grade clocks; a replaced or quartz-converted movement cuts value hard.
How to check yours, step by step
- Name the type. Decide whether it is a mantel or shelf clock, a wall clock, a tall case (grandfather) clock, a cuckoo, a carriage clock (small brass case with a handle on top) or an anniversary clock (a spinning pendulum under a glass dome). Each type has its own price band, shown in the first table below.
- Look at the dial. Read any name printed on the dial, usually just above or below the center or at the bottom. A retailer's name (a jeweler in a particular town) is common on dials and does not tell you who made the clock. Note whether the dial is paper, painted metal, enamel or brass with applied numerals.
- Open the back door. Most mantel and wall clocks have a hinged back or a removable panel. Inside, look for a paper label pasted to the back board. American clocks often carry printed labels with the maker's name, the city and instructions for setting the clock. A surviving label adds a little value and helps date the clock.
- Find the stamp on the movement. The movement is the brass mechanism. Shine a flashlight on the back plate and look for a stamped name or trademark: "Seth Thomas" or "S.T." with a diamond, "Ansonia", "Waterbury", "Ingraham", "Gilbert", "New Haven", the Junghans eight-pointed star, the Gustav Becker anchor with "G.B.", Kienzle, Hermle, Urgos or Kieninger. Note any serial numbers or letter and number codes next to it.
- Read the country line. "Germany" or "Made in Germany" usually means after 1891, when the United States began requiring a country of origin on imports. "Made in Germany (US Zone)" points to about 1945 to 1949, and "West Germany" or "Western Germany" to 1949 to 1990. "Made in U.S.A." on an American movement is generally twentieth century.
- Check what kind of movement it is. A brass movement with gears and a coiled spring means a mechanical clock. A small black plastic box with a battery means quartz. If you see a quartz box fitted in an older case, the original movement was taken out, and the clock is now valued mostly as a case.
- Count the winding holes. One hole usually means time only. Two means time and strike (hours and half hours on a bell or gong). Three means a chiming clock, such as Westminster chimes, which are more complex and more expensive to repair.
- Check if it runs. Wind it gently, set the pendulum swinging and level the clock. Listen for an even tick tock. Note whether it strikes, and whether the strike matches the time on the hands.
Clock types and what they usually sell for
These ranges are for typical examples in fair condition with original parts. Fine, early or signed pieces sit above them, and damaged or altered ones below.
| Type | Common examples | Typical value | Higher end |
|---|---|---|---|
| Wooden tambour or "camelback" mantel clock, 1910s to 1950s | Seth Thomas, Sessions, Waterbury, Hermle, Junghans | $40-150 | Rarely over $250 |
| Black mantel clock, 1880 to 1920 | Iron, slate, marble or black enameled wood with columns | $75-250 | Marble and good French examples $300-800 |
| Oak "gingerbread" kitchen clock, 1890 to 1915 | Pressed oak cases by Ansonia, Ingraham, Gilbert, Waterbury | $75-200 | Unusual case styles $250-400 |
| American shelf clock, 1830 to 1870 | Ogee, steeple, pillar and scroll, with reverse painted glass | $100-400 | Early wooden movement and named makers $500-2,000+ |
| Vienna regulator wall clock | Glazed case, long pendulum, often German, 1880 to 1920 | $200-600 | Austrian one-weight clocks in fine cases $1,000-4,000+ |
| Schoolhouse and gallery wall clocks | Round or octagonal, short drop pendulum | $75-250 | Railroad or office regulators $500-2,000 |
| Cuckoo clock, post-1945 | Black Forest souvenir carved clocks, one or eight day | $50-250 | Large musical or animated ones $300-800 |
| Cuckoo clock, 19th century | Deep-carved Black Forest, wooden plates, often huge | $300-1,500 | Exceptional carving $2,000+ |
| Carriage clock | Brass, glass sides, handle on top | $150-600 (French 19th century) | Repeaters, enamel panels $1,000-5,000+ |
| Modern carriage clock | Brass reproductions, quartz or cheap mechanical | $20-60 | |
| Anniversary (400-day) clock | Kundo, Schatz, Kern, under a glass dome | $30-150 | Early or unusual models $200-500 |
| Grandfather clock, 1960s to 1990s | Howard Miller, Ridgeway, Sligh, Emperor kits | $150-800 | Often hard to sell at all |
| Tall case clock, 18th to early 19th century | English longcase, American country makers | $1,500-8,000 | Known American makers far higher |
The pattern is easy to read. Clocks made in the hundreds of thousands, with stamped brass movements and machine-made cases, sit at $50-200 whatever their age. Value rises with hand work, early dates, fine case wood or marble, and complicated movements in good order.
Reading the movement and dial marks
The stamp on the back plate is the most reliable clue. The table summarizes the names most often found and what they usually mean for value.
| Mark on the movement | Where and when | What it usually means |
|---|---|---|
| Seth Thomas (name or S.T. in a diamond) | Thomaston, Connecticut, from 1813; huge output | Mostly $50-250; early shelf clocks, regulators and fine chime models more |
| Ansonia | Connecticut, then Brooklyn, 1850s to 1929 | Kitchen and black clocks $75-250; figural statue clocks and crystal regulators $300-1,500+ |
| Waterbury, Ingraham, Gilbert, New Haven, Sessions | Connecticut, late 1800s to mid 1900s | Generally $40-200 |
| Gustav Becker (anchor and G.B., often with a medal mark) | Freiburg in Silesia, from 1847; joined Junghans around 1930 | Regulators and mantel clocks $100-600; fine Vienna types more |
| Junghans (eight-pointed star, often with a J) | Schramberg, Germany, from 1861 | Mostly $50-250; a few Art Deco and regulator models more |
| Kienzle | Schwenningen, Germany | Mostly $40-200 |
| Hermle, Urgos, Kieninger, Howard Miller (post-war) | Germany and the United States, 1950s onward | Modern movements; value is in the case and running order |
| Japy Freres, Vincenti, a round French "pendule de Paris" movement | France, 19th century | Often better grade; carriage and marble clocks $200-1,000+ |
Two warnings help here. First, patent dates stamped on movements are the date of the patent, not when the clock was made, so an 1880s patent date can sit on a clock from 1910. Second, many German movements carry date codes or serial numbers that collectors' charts can turn into a year. Gustav Becker serial numbers, for example, are often used to date a clock to within a few years, but the charts are approximate and best treated as a guide.
On the dial, original paint and paper dials with honest wear are preferred over repainted or replaced ones. A crisp, bright dial on an 1880s clock is often a replacement. Reverse painted glass panels on American shelf clocks are part of the value; a replaced glass is worth noting.
What drives the price
Maker and model. A known maker sets the floor; a rare model or high-grade line within that maker raises it. Seth Thomas made millions of ordinary clocks and also some very good regulators, so the name alone is not enough.
Case. Solid mahogany, walnut, rosewood, marble and well-cast bronze beat pressed oak, veneer over pine, painted iron and plastic. Cracked marble, broken feet, missing finials and replaced glass all matter.
Original movement and finish. Collectors pay for originality. A clock with its first movement, dial, hands, pendulum and finish is worth far more than one with any of those replaced. A refinished case on an early clock can cut its value by a third or more, which also applies to antique furniture in general.
Running order. A clock that runs and strikes correctly sells faster and higher, but running alone does not create value on a common model. A non-running $100 clock with a $300 repair bill is a common trap.
Size and room. Large tall case clocks and big wall regulators are hard to ship and hard to fit into modern homes. That has pulled down prices for everything except the best examples.
Why most mantel clocks sell for $50-200
The answer is supply. American factories made mantel clocks by the million between about 1870 and 1950, and German factories did the same for export. Families kept them because they were sturdy and decorative, so today many sit in every estate sale, and the pool of buyers who want a wind-up clock on the shelf is small and shrinking.
Tambour and black mantel clocks also look alike to most buyers, so there is little reason to pay more for one than another. Unless a mantel clock has an unusual case, a better-grade French or Austrian movement, a fine figural mount or a documented early date, it trades as a decorative object.
The repair cost reality
Mechanical clocks need oiling and, every few decades, a full overhaul: the movement is taken apart, cleaned, worn pivot holes are bushed, and it is reassembled and adjusted. Typical costs from a clock repair shop:
- Time-only mantel clock overhaul: $150-300.
- Time and strike mantel clock overhaul: $200-450.
- Chiming mantel clock overhaul: $350-700.
- Grandfather clock overhaul, including a house call: $500-1,200 or more.
- New mainspring, broken suspension spring or replaced pendulum leader: often $40-150 added.
For most common clocks, a full overhaul costs as much as or more than the clock will sell for. That is fine when the clock is a family piece to keep. It rarely makes sense when the plan is to sell. A buyer of a common clock will usually pay only a little more for a serviced one.
Common mistakes
- Reading the retailer's name on the dial as the maker. Many dials carry a local jeweler's name.
- Treating patent dates on the movement as the year the clock was made.
- Assuming a clock that will not run is "overwound". It is usually fully wound with a dirty, dry movement that needs cleaning, and forcing the key only adds damage.
- Refinishing the case or polishing brass movement plates to look new, which lowers collector value.
- Fitting a quartz movement in an old case to "make it work", which turns a collectible into a decorative piece.
- Paying for a full overhaul before selling a common clock, then expecting the buyer to cover it.
- Shipping a clock with the pendulum attached and the weights hanging, which damages the suspension spring and movement.
What to photograph
- The whole clock straight on, in daylight, with the door closed.
- The dial close up, showing any names, the numerals and the hands.
- The back with the door open, showing any paper label in full.
- The movement's back plate, in focus, with the stamp, trademark and any numbers readable. A flashlight held at an angle helps.
- The pendulum, weights and key, and any chime rods or gong.
- The sides and base of the case, plus any damage, missing parts or repairs.
For tall case clocks, add a photo of the hood with the dial and a shot inside the trunk. For carriage clocks, photograph the back plate through the rear glass panel.
When to get it looked at in person
Three kinds of experts help with clocks. A clock repair shop or horologist can tell you whether the movement is original and what work it needs; an estimate usually costs nothing or a modest bench fee, and repair prices are listed above. An auction house with a clocks or decorative arts department can give a sale estimate, usually at no charge from photos. A formal written appraisal for insurance or an estate costs about $150-400 for one item and is worth it only for clocks that may be worth more than about $1,000.
An in-person look is worth it for any early American shelf or tall case clock, a carriage clock with a repeat button or enamel panels, a Vienna regulator that looks hand made and finely cased, or any clock with a famous maker's name on both dial and movement. For the many common mantel clocks, an online lookup of sold prices for the same maker and style gives a fair idea. If the clock came with a pocket watch or wristwatch in the same estate, see our guides to old pocket watches and inherited watches, which often hold more value per inch than any clock.
