A chest can look Georgian because it has swan-neck handles and bracket feet, yet have been made a century later. Equally, a plainly restored table may carry far more genuine history than its polished surface suggests. Learning how to date antique furniture means looking beyond style alone and reading the object as a whole: its construction, materials, proportions, wear and the evidence left by generations of use.

For most buyers, an exact year is neither possible nor necessary. A well-supported date range, such as late 18th century, circa 1880 or mid-20th century, is more honest and more useful. It helps you understand what you are buying, assess whether the details belong together, and appreciate the craftsmanship that gives an antique its presence in a modern home.

Start with the difference between age and style

In the trade, an antique is generally understood to be at least 100 years old. Vintage usually describes pieces from a more recent past, while a reproduction is made later in the style of an earlier period. These are useful distinctions, but furniture does not always sit neatly in one category.

A Victorian revival cabinet may borrow Georgian motifs. An Edwardian maker may use an older construction method. A mid-century sideboard may have had new handles fitted in the 1970s. Style provides a starting point, not a verdict. Think of it as a clue that needs to agree with the timber, joinery and hardware before it can support a date.

It is also worth separating “original” from “untouched”. Many genuinely old pieces have been repaired, re-lined, re-polished or adapted during their lives. Sensitive restoration does not remove their age or charm. What matters is whether those changes are clearly understood and proportionate to the piece.

How to date antique furniture through construction

Construction is often the most reliable place to begin because it is harder to imitate convincingly than decorative detail. Open drawers, turn the piece around where possible, and inspect places that were never meant to be on show: drawer sides, undersides, backboards, interiors and the base.

Read the joinery

Hand-cut dovetails are one of the best-known signs of earlier craftsmanship. Before machinery became widespread, dovetails were individually sawn and chiselled, so they tend to vary slightly in size and spacing. Their irregularity should look purposeful, not crude. Very uniform dovetails usually indicate later machine production, although good cabinetmakers continued to use hand methods long after factories had adopted machinery.

Look too at the way rails, legs and panels meet. Mortise-and-tenon joints, wooden pegs, hand-planed surfaces and small variations in thickness can all suggest hand work. By the later 19th century, machine-cut joints and more standardised components become increasingly common. A mixture is possible, especially in transitional periods or workshop-made furniture.

Screws provide another useful guide. Early screws were handmade, often with uneven threads and off-centre slots. Later 19th-century screws became more regular as industrial production improved. Modern screws with sharp, consistent threads and bright finishes are usually evidence of a later repair, not necessarily a reason to dismiss the furniture. The key question is whether they are holding an old structure together or pretending to prove an older date.

Examine the back and base

The back of a cupboard or chest is rarely glamorous, but it can be exceptionally revealing. Earlier boards are often wide, with saw marks, shrinkage and small irregularities. Later furniture may use narrower, more even boards. Plywood and modern sheet materials are clear signs that at least that element is 20th century or later.

Do not expect an old backboard to be pristine. Timber moves with changing humidity, and backs were commonly replaced when furniture was restored or altered. Check whether the board fits naturally within the frame and whether its fixings make sense for the rest of the piece.

Undersides can show old tool marks, accumulated dust, oxidised timber and long-term wear around feet. They should not look artificially distressed. Fresh dark stain, manufactured-looking wormholes or uniformly abraded edges are warning signs that a surface may have been aged for effect.

Identify the timber, but use it carefully

The species of wood can narrow a date and suggest where a piece was made. Oak was widely used in British furniture from the 16th and 17th centuries, while walnut became fashionable in the late 17th and early 18th centuries. Mahogany rose to prominence through the 18th century, prized for its rich colour, strength and suitability for fine carving. Satinwood, rosewood and other imported timbers appear in refined furniture of the late Georgian, Regency and Victorian periods.

However, timber alone is not a dating certificate. Old furniture may be veneered over a cheaper carcass wood, and later makers often used older-looking species. The choice of timber should be read alongside form and construction. A mahogany veneer with a chipboard core is obviously not Georgian, while a pine secondary timber inside a mahogany chest may be entirely consistent with an 18th- or 19th-century piece.

Veneer can be especially informative. Early veneers were hand-cut and may be thicker than later examples, with subtle unevenness at the edges. Inlay and stringing should sit comfortably within the surface rather than look applied as a decorative afterthought. Small losses, lifting or shrinkage around the veneer can be part of an honest age story, provided the structure remains sound.

Look at handles, locks and decorative details

Furniture hardware is often replaced because it wears out, goes out of fashion or is removed for reuse. Treat handles, escutcheons and knobs as supporting evidence rather than the sole basis for a date.

Original brassware often leaves a shadow or outline in the drawer front where it has protected the wood beneath from light and polish. Extra holes behind a handle may show that fittings have been changed, which is common and not inherently problematic. Locks can also be replaced, but an old lock plate, keyhole shape and the patina around it can still offer useful clues.

Carving, moulding and feet help place furniture within a design period. Cabriole legs, for example, appear across several 18th-century styles, while turned legs, reeding, marquetry and Gothic revival carving each had their moments of popularity. The important test is coherence. Are the feet, drawer construction, handles and timber all telling a broadly similar story? If every feature points to a different century, investigate further.

Learn to recognise honest wear

Genuine wear is concentrated where hands and feet have repeatedly met the furniture: drawer pulls, chair arms, table edges, lock surrounds, lower rails and feet. It develops gradually and unevenly. The mellow surface of old timber is often described as patina, but patina is more than a dark colour. It is the softening, oxidation and subtle variation created by time, light, polish and use.

Wormholes need particular care. Old flight holes can support a story of age, but they do not date a piece on their own. Woodworm may have affected a later object, and some reproductions are deliberately peppered with artificial holes. Fresh dust near holes suggests active infestation and should be assessed before bringing furniture into the house.

A beautifully restored surface can still retain its character. Conversely, an aggressively stripped and re-stained finish may obscure useful evidence. When considering a purchase, ask what has been done, why it was done and whether the restoration respects the original proportions and materials.

Build a date range, not a single claim

The most dependable assessment comes from combining evidence. A useful inspection sequence is to consider the silhouette first, then the timber, joinery, backs and undersides, hardware, and finally the pattern of wear. When those details align, a confident period attribution becomes possible.

Provenance can strengthen that assessment. A family history, old paper label, retailer stamp, inventory number or maker’s mark can be valuable, though none should be accepted without scrutiny. Labels can be lost, moved or reproduced. A documented maker is exciting, but a well-made, unattributed piece can still be the more compelling object for a home.

Photographs are helpful when buying online, but they cannot replace close inspection. Ask for clear images of drawer joints, backs, bases, locks, labels and any damage or repairs. Reputable dealers will describe condition plainly, including later alterations, because confidence comes from accurate presentation rather than perfection.

When expert advice is worth seeking

For everyday buying, learning these visual cues will take you a long way. For a potentially significant item, especially one carrying a high price, an unusual maker attribution or possible museum-level importance, seek specialist advice. An experienced antique dealer, restorer or furniture historian can assess details that photographs may conceal, including timber movement, tool marks, structural changes and regional characteristics.

At MN Interior Antiques, we believe the best pieces are not simply old. They are objects with a believable story, good proportions and a place in the life of a room. Whether you are drawn to a Georgian chest, an Arts and Crafts chair or mid-century furniture with a quieter kind of history, allow yourself time to look closely. The details beneath the surface are often the details that make a piece worth living with.
