How to Tell if Furniture Is Antique: 7 Tests Anyone Can Do at Round Top

You're standing in a booth at the Round Top antique show, looking at a chest of drawers with a $2,800 price tag. The dealer says it's 19th century American. It looks old. But is it actually old, or is it a reproduction that's been made to look old?

The price difference between a genuine antique and a well-made reproduction can be 5x to 10x. A real 1840s chest of drawers might be worth $2,500-$4,000. A modern reproduction made to look like one is worth $300-$500. Learning to tell the difference is the single most valuable skill you can bring to any antique show.

You don't need to be an expert. You don't need a magnifying glass or a black light. These seven tests use your eyes, your hands, and your nose — tools you already have. By the time you finish this article, you'll know more about evaluating furniture than 90% of the people walking through Round Top.

A Quick Note Before We Start

No single test is conclusive. Real antiques can fail one or two of these checks and still be genuine. Reproductions can pass some of them. The power is in combining all seven. If a piece passes five or six of these tests, you're probably looking at the real thing. If it fails four or five, ask more questions before you spend real money.

Also: there's nothing wrong with buying reproductions if you love the look and the price is right. The problem is paying antique prices for reproduction quality. These tests protect you from that.

Test 1: Check the Joinery

This is the single most reliable indicator of age. How the pieces of wood are joined together tells you more about when a piece was made than almost anything else.

What to Look For

Dovetail joints are the telltale. Pull out a drawer and look at the corners where the front and side panels meet.

Hand-cut dovetails (pre-1860s): Irregular, slightly uneven spacing. The pins and tails won't be perfectly identical. The scribe lines (the marks the craftsman used to guide the cuts) may be visible. The angles tend to be more extreme and less uniform. This is the fingerprint of handwork — no two joints are exactly the same.
Machine-cut dovetails (1860s-1900s): Uniform, evenly spaced, precisely identical. The pins and tails are symmetrical. These were cut by industrial equipment and are consistent across all drawers in the piece. Machine dovetails indicate the piece was made after the mid-19th century — still potentially antique, but industrial rather than handcrafted.
No dovetails at all: If the drawer corners are joined with staples, nails, or simple butt joints held by glue, you're almost certainly looking at modern production furniture. Walk away from any dealer calling that piece antique.

Also Check

Mortise and tenon joints in chairs, tables, and case pieces. Old mortise and tenon joints were cut by hand and show slight irregularity. They fit tightly because the wood has had decades or centuries to settle into itself.
Pegged joints: Wooden pegs (also called treenails) securing joints are a strong indicator of pre-industrial construction. The pegs will be slightly off-center and not perfectly round — because they were hand-shaped.
Screws at the joints: If the joints are reinforced with Phillips-head screws, the piece dates to 1930 at the earliest. Phillips screws were invented in 1930 and didn't become common until the 1940s.

Test 2: Look at the Wood

The wood itself tells a story if you know how to read it.

Old-Growth vs. New Lumber

Furniture made before the mid-1900s was typically built from old-growth timber — trees that grew slowly over hundreds of years in dense forests. Old-growth wood has tight, closely spaced grain lines. Modern lumber comes from fast-growth plantation trees and has wider, more widely spaced grain.

Pull out a drawer and look at the end grain (the cross-section of the wood, visible at cut edges). Tight, narrow growth rings suggest older wood. Wide, open growth rings suggest modern lumber.

Patina vs. Stain

Genuine patina is what happens when wood oxidizes over decades of exposure to air, light, and handling. It's a gradual, uneven darkening that's deepest on exposed surfaces and lightest in protected areas (undersides, insides of drawers, backs of pieces).

Key differences:

Real patina: Uneven coloring. The top surface is darker than the sides. The inside of drawers is lighter than the outside. Areas that were touched frequently (drawer pulls, arm rests, seat edges) show a smooth, burnished quality. Patina develops unevenly because exposure is uneven.
Fake aging (stain applied to look old): Uniform coloring, even in areas that wouldn't have been exposed to light or handling. If the inside of a drawer is the same color as the top surface, someone applied finish everywhere. Real antiques don't age uniformly.

Secondary Woods

Many antique furniture makers used expensive, attractive wood for visible surfaces (mahogany, walnut, cherry) and cheaper wood for hidden structural parts (pine, poplar, tulipwood). Check the drawer bottoms, the back panels, and the interior structure. Finding two different species of wood — nice wood in front, plain wood in back — is a positive sign that the piece was made by someone who understood traditional furniture construction.

Test 3: Examine the Hardware

Hardware evolves on a predictable timeline. The pulls, hinges, screws, and locks on a piece of furniture can date it with reasonable precision.

Screws

Screw Type	Date Range
Handmade screws (irregular threads, flat bottom, off-center slot)	Pre-1850
Early machine screws (pointed tip, but slightly uneven threads)	1850-1870
Modern machine screws (perfectly uniform threads, pointed tip, centered slot)	1870+
Phillips head screws	1930+

Finding handmade screws is a strong indicator of genuine early antique construction. The slot in the screw head will be slightly off-center, and the bottom of the shaft will be flat or blunt rather than pointed.

Pulls and Knobs

Bail handles (the swinging type): Common on 18th century and early 19th century American and English furniture. The backplate should show wear consistent with decades of hands pulling on it.
Wooden knobs: Popular in the early-to-mid 1800s, especially on country and Shaker-style pieces. Hand-turned knobs will be slightly irregular — no two are perfectly identical.
Pressed glass and porcelain knobs: Common from the mid-1800s through early 1900s.
Modern reproduction hardware: Often cast from molds of antique originals. Feels lighter, sharper-edged, and less substantial than the real thing. Reproduction hardware has a flat, uniform finish rather than the slight variations of aged metal.

The Replacement Question

Original hardware is ideal, but many genuine antiques have had their hardware replaced over the decades. That's normal — people have been updating furniture hardware for as long as furniture has existed. Look at the holes: if there are extra holes, filled holes, or mismatched holes, the hardware has been changed at some point. That doesn't mean the piece isn't antique. It just means the pulls aren't original.

Test 4: Feel the Surfaces

Put your hands on the piece. Run your fingers along edges, across surfaces, underneath tops, and along legs. Touch is one of the most underused evaluation tools.

Real Wear vs. Manufactured Distressing

Genuine wear patterns develop where people actually touched, used, and bumped into the furniture over decades:

Drawer edges are smooth and slightly rounded from being pulled open thousands of times
The front edges of table tops are softer than the back edges (people sit at the front)
Chair arm ends are worn smooth where hands rested
Stretchers between chair legs show wear where feet rubbed against them
The area around a keyhole shows scratches and wear from decades of key insertion

Manufactured distressing is applied randomly or uniformly:

"Wear" appears in places that wouldn't naturally experience friction
Edges are beaten or dented in a pattern that looks deliberate
The distressing is consistent across the whole piece rather than concentrated in logical high-traffic areas
Sanded-through paint reveals surprisingly clean, new-looking wood underneath

Here's a good rule of thumb: real wear makes sense. It appears where people would have touched, leaned, bumped, or rubbed against the furniture during decades of normal use. If the wear pattern doesn't make logical sense, it was probably put there on purpose.

Edges

Run your fingers along the edges of shelves, tabletops, and drawer fronts. Old furniture develops soft, gently rounded edges from decades of handling. New furniture — even distressed new furniture — tends to have sharper, more defined edges. This is subtle, but once you learn to feel the difference, it's hard to miss.

Test 5: Check the Back and Underside

This is where the real evidence lives. Dealers know that buyers look at front surfaces. They know fewer buyers flip the piece over or pull it away from the wall.

What the Back Tells You

Unfinished, rough-sawn backs: Common in genuine antiques. Furniture makers rarely finished surfaces that faced the wall. If the back is rough, shows hand-saw marks (slightly wavy, irregular cuts), and is a different wood than the front, that's consistent with period construction.
Smooth, finished backs: More common in modern furniture. If the back panel is smooth, sanded, and finished on both sides, the piece was likely made recently.
Thin plywood or composite backs: Modern. Antique furniture used solid wood panels for backs, not plywood (which wasn't commercially available until the early 1900s) or particle board (mid-1900s).

What the Underside Tells You

Flip the piece over or get on the floor and look up at the underside of tables, chairs, and case pieces.

Old paper labels or stamps: Manufacturers, retailers, or customs agents sometimes labeled furniture on the underside. These labels yellow, crack, and deteriorate over time. A crisp, bright label is likely modern.
Chalk marks, pencil marks, or Roman numerals: Period furniture makers often marked components during assembly. These marks should look old — the graphite or chalk will have faded and partially absorbed into the wood.
Tool marks: Hand-plane marks (slight ridges and scallops) indicate pre-industrial construction. Circular saw marks (curved lines) indicate the piece was made after about 1830 when circular saws became common. Band saw marks (straight parallel lines) indicate post-1850s.
Consistent aging: The underside should show the same general character of age as the rest of the piece — dusty, dry, darkened by oxidation. If the underside looks conspicuously fresh and clean while the visible surfaces look old, something is off.

Test 6: Look for Repairs and Modifications

This one surprises people: evidence of old repairs is actually a good sign.

Furniture that has been in use for 100+ years has almost certainly been repaired at some point. A re-glued joint, a replaced runner on a drawer, a patched veneer — these are signs of a piece that has been lived with and maintained over a long life. The absence of any repairs on a supposedly 150-year-old piece should make you more suspicious, not less.

What to Look For

Re-glued joints: Visible glue squeeze-out, especially old hide glue (dark, amber-colored) rather than modern white or yellow carpenter's glue.
Replaced drawer runners: The runners (the strips of wood that drawers slide on) wear out and were commonly replaced. New runners on an old piece are normal.
Added hardware: As mentioned above, hardware replacement is common and doesn't diminish authenticity.
Structural modifications: Extra bracing, added support blocks, or reinforced joints suggest the piece has been maintained over time.

Red Flags

New wood used to replace major structural components (new legs on an old table, for instance) — at some point, enough replacement makes the piece a different piece entirely.
Fresh-cut wood visible inside joints that should have been assembled 100+ years ago.
Modern adhesives (bright white or yellow glue) on joints that should be original construction.

The judgment call: minor repairs using old methods and old materials are consistent with genuine age. Major reconstruction using modern materials warrants a conversation with the dealer about what exactly you're buying.

Test 7: Trust Your Nose

This is the weirdest test on the list, and it works.

Old wood smells different from new wood. Genuinely old furniture has a distinctive, dry, slightly musty scent — the smell of wood that has been oxidizing for decades. Some people describe it as "attic smell" or "grandmother's house smell." It's not unpleasant. It's the smell of age.

New wood, new finishes, and new stains smell like chemicals. Fresh lacquer, polyurethane, wood stain, and new-growth lumber all have sharper, more acrid scents. If you open a drawer on a "19th century" piece and it smells like a hardware store, you have a problem.

This test works best on case pieces with drawers or enclosed spaces. Open a drawer, stick your nose in, and breathe. An old drawer will smell like old wood — dry, dusty, faintly sweet. A new drawer dressed up to look old will smell like finish, stain, or fresh sawdust.

Is this 100% reliable? No. A genuinely old piece that has been recently refinished will smell like new finish. A reproduction that has been stored in a barn for a few years might pick up some musty character. But combined with the other six tests, your nose gives you one more data point.

What to Do When You're Not Sure

You've run all seven tests, and the results are mixed. Three tests say yes, two say no, two are inconclusive. Now what?

Ask the Dealer

Good dealers welcome questions. Ask directly:

"Can you tell me about the provenance of this piece?"
"What period would you date this to?"
"Has anything been replaced or restored?"
"Where did you source this?"

A knowledgeable, honest dealer will answer these questions confidently and specifically. They'll say "I bought this from an estate sale in New Braunfels, it was in the family since the 1920s" or "This is an English pine piece, probably 1830s-1840s, I sourced it from a dealer in London." Vague answers like "it's old" or "it's been around a while" should make you cautious.

Check the Price

Price isn't proof of authenticity, but it's a useful reality check. If a piece is priced well below what genuine examples of that type and period typically sell for, ask yourself why. Sometimes you've found a bargain. Sometimes the price is low because the piece isn't what it appears to be.

Get a Second Opinion

If you're considering a significant purchase (four figures or more), walk away and think about it. Visit other booths that sell similar items and compare. Talk to another dealer who specializes in the same period or style. At Round Top, expertise is everywhere — use it.

Trust Your Gut

After you've done the tests and asked the questions, trust your instinct. If something feels off about a piece — the aging doesn't look quite right, the dealer is vague, the price seems too good — it's okay to walk away. There are 1,500 vendors along the Round Top corridor. Another piece will come along.

Where to Practice at Round Top

If you want to train your eye, these venues offer a good mix of genuine antiques and other inventory that will give you practice distinguishing the real from the reproduced:

Marburger Farm is the gold standard. The inventory here is heavily vetted, and most vendors are specialists who can authenticate their pieces. Walk through Marburger slowly, handle the furniture, look at the joinery, feel the surfaces. This is your reference library for what genuine antiques look like up close.

The Arbors carries a wide range — genuine antiques alongside vintage, reproduction, and decorative items. This variety makes it an excellent training ground. Challenge yourself: walk through a booth and try to identify which pieces are antique, which are vintage (old but not antique), and which are reproduction or new.

The Warrenton field venues (Bar W Field, The Horseshoe) are where you'll find the most diverse mix of inventory quality. Genuine antiques sit next to vintage pieces, handmade items, and some reproduction work. The price points are lower, which also means the stakes for practicing your evaluation skills are lower. This is a good place to pull out drawers, flip things over, and run through all seven tests without feeling like you're handling a $5,000 piece at Marburger.

One Last Thing

Learning to evaluate antique furniture is a skill that compounds. The more pieces you examine, the faster and more confident you become. Your first Round Top trip, you'll be cautiously pulling out drawers and second-guessing yourself. By your third trip, you'll be able to spot a genuine piece from across a tent.

The goal isn't to become an expert overnight. The goal is to know enough to ask the right questions, avoid the obvious mistakes, and feel confident spending money on pieces you love.

Round Top is one of the best places in the world to develop this skill, because the concentration of quality antiques — and knowledgeable dealers — is unmatched. Every booth is a classroom if you treat it like one.
