Sellers use the words "antique" and "vintage" loosely, and many objects that look old were made to look that way. Learning to read real age is the most useful skill in collecting, because it protects you from overpaying and helps you recognise a genuine find. This guide covers what the terms mean and the practical clues that separate old from new.

What the words mean

Term	Usual meaning
Antique	At least 100 years old
Vintage	At least about 20 years old, and less than 100
Retro	Newer items made in an older style, or the style of a recent past era, often the 1950s to 1980s
Reproduction	A copy of an older design, made later, usually openly sold as a copy
Fake or forgery	A copy made or altered to deceive buyers about its age or maker

The 100-year definition of "antique" is widely used, and it is the threshold United States customs law uses for duty-free import of antiques. "Vintage" has no legal definition. The 20-year minimum is a common convention, used by marketplaces such as Etsy, but some dealers apply it more loosely.

A few other terms are worth knowing:

Period piece. Made during the era whose style it shows, such as a Georgian chair actually made in the Georgian period.
Revival or later copy. Made in an earlier style long after that style was first fashionable. Victorian makers produced many pieces in 18th-century styles. These can be antiques in their own right, but they are not period pieces.
Marriage. An object assembled from parts of two or more different pieces, such as a bookcase top on an unrelated desk base.
Made up. A piece built using some old timber or parts, but not as an original whole.

None of these is automatically bad. A good reproduction just shouldn't be priced as an original.

Signs of genuine age

Real age leaves marks that are hard to imitate convincingly. The key idea is logic: genuine wear appears where hands, feet and use would naturally cause it, and nowhere else.

Wear in the right places

Think about how the object was used, then look where that use would show:

Chairs: the front stretcher worn by feet, the top rail and arm ends smoothed by hands.
Tables: edges softened where people sat, feet scuffed at floor level.
Drawers: runners and the bottom edges of drawer sides worn down from sliding in and out.
Handles and knobs: the wood or finish around them worn from fingers.
Ceramics and glass: fine scratches and wear on the foot rim or base, where the piece was set down many times.

Wear on genuine pieces tends to be soft, gradual and uneven. It fades out gently rather than stopping at a sharp edge.

Oxidation and patina

Exposed surfaces darken and change colour over time. On furniture, the unfinished wood on the back, underside and inside of drawers usually darkens to a dull, dry tone. A freshly cut surface is pale. If you see bright, clean wood where a piece should have been exposed to air for a century, ask why.

On metal, an even, mellow patina builds up in recesses and softens on high points that were handled. A uniform chemical colour across the whole surface is more suspicious.

Signs of artificial distressing

Fakers and some furniture makers "age" new pieces deliberately. Common techniques leave telltale signs:

Wear that's everywhere at once. Even dents and scratches spread across surfaces that wouldn't normally be touched, such as the middle of a cabinet side.
Repeated patterns. Dents from hitting the wood with chains, keys or tools often come in clusters of similar shapes.
Fake wormholes. Woodworm larvae tunnel along the grain in winding paths, and the round holes you see are where adult beetles left. Holes drilled or shot into wood go straight in, and sometimes appear on surfaces where the tunnels underneath would have to be impossible.
Paint or stain in the wear. Real wear removes finish. On a faked piece, stain sometimes collects inside scratches that were made before it was applied.
Uniform "grime". Dark wax or stain rubbed into corners to look like dirt, with a colour that doesn't match the rest of the surface.

Construction methods

How a piece was put together often tells you more than its style. Methods changed as hand tools gave way to machines, so the way a joint was cut can rule a date in or out. For furniture specifically, see our detailed guide on how to identify antique furniture.

In brief, look for:

Hand-cut joints, such as dovetails with slightly uneven spacing and a scribed guide line.
Hand-tool marks, such as the gentle ripples of a hand plane or straight saw marks, rather than the arcs of a circular saw.
Irregular thickness in boards and panels, which shows they were worked by hand.

Materials and fasteners

Some materials and hardware simply didn't exist before a certain point, so they work as dating clues.

Screws: early handmade screws have uneven threads, blunt ends and slots often cut off-centre. Machine-made pointed screws became common from the mid-19th century. Phillips (cross-head) screws were introduced in the 1930s, so they shouldn't appear as original fixings on anything older.
Nails: hand-wrought nails have irregular square shanks and hammered heads. Cut nails followed, then round wire nails, which became standard in the late 19th century.
Man-made boards: plywood came into wide furniture use in the 20th century. Particleboard and MDF are later still. If they're original to a piece, the piece is not an early antique.
Staples and modern glues: staples, hot glue and white PVA glue in original joints point to recent work.
Plastics and synthetic fabrics: these date a piece to the 20th century or later, unless they're clearly replacements.

Replacement parts are common on genuine antiques, so one modern screw doesn't condemn a piece. What matters is whether the original structure is old.

Common reproduction tells

Across categories, reproductions often share a few habits:

Too perfect. Identical, crisp details where handmade originals would vary slightly.
Wrong weight. Many reproductions in cast iron, brass or glass feel lighter or heavier than originals. Compare with a known genuine example if you can.
Rough or grainy casting. Cast metal reproductions, made from moulds taken from an original, often show soft detail and a sandy surface.
Printed instead of painted. Under magnification, many reproduction prints, labels and decorations show tiny dots in a regular pattern, a sign of modern printing.
Removable origin labels. A paper sticker reading "Made in…" on a modern import is easy to peel off, so look for the residue.
Too much age on a cheap object. Heavy distressing on a simple everyday item can be a sign that it was aged to sell.

Pottery and porcelain have their own clues, especially marks. Our guide to pottery and porcelain marks explains them. Glass also has well-known reproductions, covered in Depression, carnival and milk glass.

Put the clues together

No single sign proves age. A genuine antique can have a replaced handle, and a clever fake can have an old screw. Experienced collectors look for agreement: style, construction, materials, wear and marks should all tell the same story. When one clue contradicts the rest, investigate further.

Tip: Examine the parts nobody was meant to see: the back, the underside, inside drawers and behind panels. Fakers often spend their effort on the visible surfaces and leave the hidden ones looking new.

An app such as AI Antique can suggest a likely period, country of origin and the reasoning behind it, which helps you know what to look for. Check its suggestion against the physical evidence above. If a piece may be valuable and you still have doubts, a specialist dealer, auction house or accredited appraiser can examine it in person. Once you're confident about age, our guide on how much your antique is worth explains how to price it.
