Every seasoned antique buyer has a story about the one that got away, the piece they walked past at an estate sale because it looked “too plain,” only to see it sell weeks later for ten times what the seller was asking. Coincidentally, they often have the other side of the tale: the one that they overpaid for because, “it was old and no one in the room seemed to know better.”
The gap between those two outcomes almost never comes down to luck. It’s simply a matter of knowing what to look for, what the details are that make an antique worth its weight in gold, and what isn’t. I have been doing furniture and other object restoration for a number of years, and in the process I’ve seen a few designs of furniture and objects that come up over and over again, and once you recognize them you see them everywhere. This guide explains step-by-step what those patterns are.

Start With Construction, Not Appearance
The short answer: how a piece was built tells you more about its age and value than how it looks on the surface.
Surface details like finish, color, and style are the easiest things for a reproduction to fake convincingly. Methods of construction are much more difficult to falsely emulate, as they involve the actual techniques, tools and material limitations of the time period, not just the illusion or appearance of them. First check the piece itself and how it was constructed.
Rotate the object, open drawers and look under. True antique furniture exhibits evidence of handmade work: joints that may be slightly uneven, tool marks that are not always consistent, and handmade construction that is not as precise as machine-made. However, if a piece is constructed with the degree of perfection; perfect joints, perfect even symmetry by machine is often a warning sign instead of a comfort, especially if it is offered as being significantly older than it would be with the help of mass production techniques.
Check the Joinery
Joinery is one of the best clues a buyer can use, as the styles of joinery developed in relatively well-established ways over time, and no other method of joinery is as easy to replicate convincingly as the dominant method of the time.
Dovetail joints, commonly found on drawers, are a particularly useful clue. Hand cut dovetails, which were used before the mid-1800s, vary in size and spacing because each dovetail was cut by hand. Afterwards, dovetails were made by machine, which results in uniform and evenly spaced dovetails. Whether or not the seller states the piece is “old” or “new,” a drawer with slightly uneven, individually cut dovetails is a more telling sign of true age than a drawer with perfectly matched, machine-cut dovetails.
Mortise-and-tenon joints, common in older tables and chairs, should show some wear and settling consistent with age, slight gaps, minor movement, a joint that has clearly flexed and aged over decades rather than one that looks freshly assembled.
Examine the Materials
The kind of wood used, hardware, and other materials that may have been used in a piece can help date it, and also help determine its authenticity, because some materials became in or out of use at fairly recognisable periods of the past.
In general, solid wood construction, as opposed to veneer over inferior wood or particle board, is a good indicator of quality and age, although it is noted that there are good examples of veneer construction over lower quality wood or particle board which have been used skillfully and for a long time. More important is that the veneer is over solid wood that has age-appropriate use and wear, rather than a modern reproduction that is particle board with low quality veneer that mimics an antique appearance.
Hardware, hinges, pulls, screws and nails provide some of the most obvious dating clues. The nails are hand-made, with slightly irregular heads and slightly irregular nails, indicating that they are not from the industrialized era, when nails and screws were machine-cut and uniform, on the other hand, the nails are not perfectly modern. Mismatched hardware isn’t always a bad sign, as over the course of many years, replacement hardware is natural and expected, but hardware that seems to be relatively modern on a machine that supposedly is much older does warrant further investigation.
Look for Genuine Patina, Not Artificial Aging
Patina, which is the natural surface changes that wood, metal and other materials undergo over decades of use, is one of the most difficult of the qualities to convincingly reproduce, despite many attempts.
Authentic patina is irregular and makes logical sense: darker where it was used more often – such as on drawer pulls and armrests – lighter where it has been protected or less used – and even on the consistency of the use of the object over its lifetime. A good way to tell is when artificially aged pieces have an even patina or the aging is focused in areas that would not have normally been touched or exposed to light in that object’s normal life, “distressed” edges that look more like a decorative pattern than a functional one.
Shake hands with the surface. Real age has a smooth feel where it has been used for decades in high contact areas, and artificially distressed sanded, stained, and/or chemically treated surfaces tend to be rougher or more obviously textured than real age would be.

Search for Maker’s Marks and Labels
A maker’s mark, manufacturer’s label or stamped signature is found on many valuable antiques and discovering one can instantly make a difference in the confidence you have in identifying the item as well as its value. They’re frequently on the bottom of furniture, inside drawers, on the back of a mirror or frame, or stamped into metal pieces, such as hinges or locks.
A legible maker’s mark enables research into the particular manufacturer, workshop or area of production in order to establish an approximate date of production, and sometimes the name of a particular maker whose work is documented and known to have value. Even if a mark is only partially present or partially worn away, don’t hesitate to take a photo and do the research before deciding to buy, as it can have significant implications on what a fair price is.
Whether or not there is a maker’s mark does not necessarily rule something out. Many good period pieces, especially folk furniture and local craftsmanship, were never marked. But when a mark is present, it’s one of the most reliable pieces of evidence available.
Assess Structural Integrity and Restoration Potential
A valuable antique doesn’t have to be in perfect condition, but it must be structurally sound enough to restore properly, or already restored in an age and material appropriate manner. Test for stability: if a chair wobbles when you sit on it, does it wobble in a way that is not a normal settling process, but does indicate loose joints? Does a cabinet door hang properly or has it been warped so it doesn’t work well?
Past repairs need to be looked at very closely. It is generally agreed that repairs made with period appropriate materials and methods hold up much better than repairs using modern materials that conflict with the original construction, mismatching wood species, obvious modern glue or hardware that does not match the period. This is one of the key aspects where a skilled restorer’s eye is essential, deciding between a well maintained item throughout its useful life and one that may have been parlayed for years and years with a patch here and a patch there that has left the item neither whole or of long term value.
Watch for Common Red Flags
Some warning flags appear in all reproductions and misrepresentations and knowing the signals can help you to avoid a costly mistake. Watch for pieces that have unusually even wear that might suggest they are not all original to the item, hardware that appears to be much newer than the piece it’s attached to, construction that doesn’t match what is expected for the time period and sellers that can’t be specific or consistent about the piece’s origin or history.
Another way to price is to use a signal as well. A price that is dramatically different than similar verified antiques are selling for should be viewed with suspicion and not as an incredible deal, as there are legitimate antiques that can be on sale, but they are not as common as the saying “too good to be true.”
Why Expert Evaluation Still Matters
But despite all these signs, some certifications really need an expert eye, especially when it comes to valuable items where an incorrect assessment can cost thousands of dollars. It takes years of hands-on experience to read with reliability construction details, wood species and period-specific techniques, particularly if a buyer might encounter the wide range of regional and international styles.
When assessing any item you think might have real value, or you want to restore something you’ve already bought, a professional appraisal is a great way to safeguard your investment and preserve the piece’s integrity.
