Antiques, items more than 100 years old, carry a kind of history that new furniture cannot fake, but the market is full of pieces that try. Reproductions, distressed reproductions, and outright fakes sit next to genuine antiques at thrift stores, flea markets, and estate sales, and the price difference is usually large enough to hurt when a buyer guesses wrong. The good news is that genuine pieces leave physical evidence of their age, and six checks catch most fakes within a few minutes.
The checks cover definition, research, construction, wood and patina, hardware and finish, and a final buying routine. None requires a specialist, though a magnifying glass helps. When a genuine piece does come home, the work is not over: restoring old hardware with professional techniques for cleaning, polishing, and preserving antique doorknobs, hinges, and cabinet hardware keeps the find functional for another century.
What Counts as an Antique
The word antique has a working definition: an item made more than 100 years ago. The cutoff matters because it sets the market. A 90-year-old chair is vintage, a 110-year-old chair is antique, and the difference can multiply the price. Antiques include furniture, decor, art, tools, and lighting; vintage covers everything from about 1920 to 2000.
The 100-Year Rule
Use the rule as a filter, not proof. A seller who cannot say when a piece was made is a reason to slow down, and a piece labeled antique that has machine-cut dovetails and Phillips-head screws has a problem, because those details date it after the 1930s. Furniture is the easiest category to age, since joinery changed in well-documented steps.
Antique vs Vintage vs Reproduction
Vintage items are collectible in their own right and much cheaper, which makes them a sensible target for many rooms. Reproductions are new pieces made to look old, and they are legitimate when labeled and priced as such. Trouble starts when a reproduction is sold as original, and buyers defend against that by learning what originals actually look like. A homeowner can recreate the look of an antique closet door with new lumber and aged hardware, which makes a useful study in how reproduction differs from the genuine article.
Research Before You Shop
The pros who buy and sell antiques for a living all start the same way: they read. Books, auction catalogs, museum collection databases, and price guides teach the forms, woods, and hardware of each period, so a fake stands out the way a wrong word does to an editor. The goal is not encyclopedic knowledge but enough familiarity to notice when something does not fit.
Building a Reference Library
Start with two or three books on the categories you buy most, such as furniture or lighting, plus a price guide with photos. Auction house archives are free and searchable, and they show what real pieces sold for while training the eye on construction details. Trade coverage helps too: This Old House’s how to spot a fake antique walks through the same tells the pros check.
Learning the Hallmarks of Each Period
Each era left fingerprints. Eighteenth-century case pieces used hand-cut dovetails, rose-head nails, and hand-planed surfaces; Victorian furniture leaned on machine carving and pressed decoration; early twentieth-century pieces used screws with gimlet points. A chair claimed to be from 1800 that has flat-head machine screws and a plywood panel is a contradiction, and knowing the hallmarks makes the contradiction obvious in seconds.
Examining Construction and Joinery
Joinery is the most reliable age test because it is expensive to fake well. Before about 1860, dovetails were cut by hand, with slightly irregular pins and tails; after mechanized production spread, dovetails became uniform, tight, and identical. A fake made yesterday can be hand-cut to mimic the look, but fakers rarely bother on inexpensive pieces, and the rest of the construction usually gives them away.
Dovetails: Hand Cut vs Machine Cut
Look at the drawer corners. Hand-cut dovetails have pins and tails of slightly different widths, with faint saw marks and chisel chatter inside the joint. Machine-cut dovetails are perfectly regular and often spaced identically across the drawer front. Machine dovetails do not make a piece worthless, but they date it firmly after the mid-1800s, which contradicts an earlier label.
Saw Marks, Nails, and Screws
Open a drawer and look at the secondary wood, the unfinished interior. Circular saw marks mean the piece was made after about 1860, when the saw became common; earlier boards show straight, faint lines from hand saws or the curved arcs of a pit saw. Nails tell a similar story: hand-forged square nails before the 1790s, cut nails with rectangular cross-sections after that, and round wire nails after about 1890. Reading those marks is faster when you know what each tool generation left behind, and the craftsmanship and practical value of antique tools explains exactly that.
Reading a Drawer Interior
The interior is the honest part of a piece. Fakes distress the outside and leave the inside pristine, or distress the inside with sandpaper in patterns no real drawer shows. Age brings honest dirt, surface oxidation, and wear in the bottom corners where hands reached in, not uniform scuffs across a panel.
Wood, Patina, and Wear Patterns
Old-growth timber is part of why antiques feel different. Trees harvested in the 1800s grew slowly, giving dense, tight-grained boards that rarely appear in modern lumber, and a century of light and air mellowed the color: mahogany deepened to a rich brown-red, oak darkened and grayed, and pine aged from cream to honey. Patina, the surface character built by handling, cannot be manufactured convincingly, which is why it is the faker’s hardest obstacle.
Reading Patina
Run your hand across the surface. A century of use wears edges, arms, and drawer pulls smooth and slightly darker; light exposure fades the top surface while protected areas keep the original color, so a genuine piece shows uneven but logical tone. A fake shows color that sits on the surface, often sprayed, with wear that does not match how the piece was actually used.
Where Real Wear Appears
Wear follows use. A dining table wears at the edges and around place settings, a desk at the writing surface and drawer fronts, a chair at the arms and seat rails. Fakers sand or beat the obvious spots and then stop, so check the places hands rarely touched: the backs of drawer sides, the underside of a tabletop, the inside of a cabinet. Antique desk identification and restoration shows how wood types, joinery methods, and period details separate a real desk from a dressed-up copy.
Hardware, Finishes, and Signs of Faking
Hardware and finish give fakes away faster than almost anything else, because they are the parts fakers replace or fake last. Genuine antique hardware is hand-forged or early cast iron and brass, with irregular surfaces; modern hardware is crisp, uniform, and often zinc or die-cast. Original finishes are shellac, milk paint, or early varnish that have aged and crazed; modern polyurethane looks and smells wrong up close.
Fasteners Tell the Story
Screws are a quick tell. Before about 1846, screws were hand-cut, with slightly off-center slots and uneven threads; machine-made screws after that are regular and sharp. A genuine antique assembled with modern Phillips screws was either repaired or faked, and a careful buyer asks which.
Finish and Smell
Old finishes feel warm and are often alligatored, a fine crackle from decades of expansion and contraction, and they smell like wax and old wood. Fresh varnish, polyurethane, or a glue smell under a drawer means recent work. Fakers also sand edges to fake wear; genuine edges are worn smooth and slightly rounded, never sharp from a belt sander.
| Indicator | Genuine | Fake |
|---|---|---|
| Joinery | Irregular hand-cut dovetails | Uniform machine dovetails |
| Saw marks | Straight hand-saw or pit-saw lines | Circular saw arcs |
| Nails and screws | Square, hand-forged; hand-cut slots | Wire nails, Phillips heads |
| Patina | Uneven, follows use | Uniform, surface-applied |
| Finish | Shellac or milk paint, crazed | Polyurethane or fresh varnish |
| Wear | On edges and handled spots | Sanded or beaten random spots |
Six Checks to Run Before You Pay
Run the six checks in order and a fake rarely survives all of them. The routine takes five minutes in a store and works for furniture, decor, tools, and lighting alike.
- Define the claim: what period and style is the seller stating, and does the piece match?
- Check joinery: open drawers and doors, and look for hand-cut dovetails and honest secondary wood.
- Read the patina: run a hand over the surface and look for wear in the right places.
- Inspect hardware and fasteners, and ask whether they match the claimed date.
- Smell and feel: old finish and old wood, or fresh varnish and glue.
- Ask for provenance: history, receipts, or a dealer who can name the period and explain the piece.
Buying With Confidence
Furniture is where most buyers start, and the stakes are highest there: how to buy an antique table: what every buyer should know runs through price checks, condition grading, and the questions to ask before money changes hands. The same discipline applies at any scale, from a $20 thrift-store lamp to a $2,000 auction piece.
- Bring a small flashlight and a magnifying glass; drawer interiors hide the evidence.
- Ask about restoration, because honest sellers disclose repairs, replaced hardware, and refinishing.
- Walk away from pressure, since genuine antiques are plentiful and the next estate sale is always a week away.
Lighting is a good category for a first antique purchase because the market is deep and the tells are the same. Antique lamps for modern homes demand the same buying, evaluating, and restoring of vintage lighting, from checking the socket and cord age to confirming the shade is original. Run the six checks, trust the joinery over the story, and the piece you bring home will still be the real thing in another hundred years.
