Not everything old is antique, and not everything antique is valuable — but the difference matters if you’re buying furniture at an estate sale, a thrift store, or anywhere secondhand. Here’s how to actually tell what you’re looking at, and what to do with that information once you know.
What “Antique” Actually Means
Technically, an item has to be at least 100 years old to be called a true antique. Furniture that’s 20-99 years old is usually called “vintage,” and anything newer that’s designed to look old is just a reproduction. None of those categories automatically mean “valuable” or “worthless” — a well-made vintage piece can be worth more than a damaged true antique, and age alone never tells the whole story.
6 Ways to Tell If Furniture Is Antique
1. Check the joinery
Flip the piece over or open a drawer and look at how it’s actually put together. Older furniture typically uses dovetail joints (interlocking, triangular “fingers” visible at drawer corners), mortise-and-tenon joints, or wooden pegs — all cut by hand, so they’re never perfectly uniform. Mass-produced modern furniture almost always uses staples, glue, dowels, or machine-cut finger joints that are suspiciously identical from one to the next.
2. Look at the screws
This is one of the fastest tells. Hand-cut screws (pre-1850s) have uneven, off-center slots and inconsistent threading. Machine-made screws from the mid-1800s on are more uniform but still have a flat head with a single slot — Phillips-head screws weren’t invented until the 1930s, so finding one is a strong sign the piece is either newer than it looks or has been repaired at some point.
3. Examine the wood itself
Solid wood with real grain variation, slight warping, or natural color differences between boards points to an older piece built before plywood and veneer became standard. Look underneath and on the back — areas that were never meant to be seen are where corners get cut on reproductions, so unfinished or roughly finished wood in hidden spots is actually a good sign on an otherwise polished piece.
4. Check for saw marks
Circular saw marks (smooth, perfectly curved lines) became common in the mid-1800s. Straight, slightly irregular marks point to an earlier hand saw or an up-and-down “sash” saw, both signs of real age. Perfectly uniform, machine-sanded surfaces with no marks at all usually mean a newer piece.
5. Look for a maker’s mark or label
Check the back, underside, or inside a drawer for a stamp, paper label, or brand. Even a partial or worn maker’s mark can be researched online and is often the single most useful clue for dating a piece and estimating value — far more reliable than guessing from appearance alone.
6. Inspect the hardware
Drawer pulls, hinges, and locks are another reliable clue, with one catch: hardware gets replaced over the years far more often than the furniture itself, so it’s a supporting clue, not a standalone answer. Original hand-forged or cast hardware tends to show slight irregularities, wear patterns consistent with the piece’s finish, and attachment points (screw holes, mounting plates) that match the furniture’s actual construction era. A pull that looks brand new on an otherwise well-worn piece, or mounting holes that don’t quite line up with visible old holes behind them, both suggest a hardware swap at some point.
How to Price or Value a Piece
Once you’ve got a reasonable sense of age, pricing comes down to three things:
- Condition. Original finish, intact joints, and minimal damage all add value. Heavy repairs, missing hardware, or water damage subtract from it — sometimes significantly.
- Maker and rarity. A documented maker or a limited production run matters more to value than age alone. A plain, mass-produced antique is often worth less than a well-made vintage piece from a known maker.
- Comparable sales. The real-world test is what similar pieces have actually sold for recently — not what a similar-looking item is listed for, which tells you what someone hopes to get, not what it’s worth.
If you want a real number rather than a rough estimate, a professional appraiser is worth the cost for anything you suspect is genuinely valuable — but for most estate-sale furniture, checking recent sold listings for comparable pieces online will get you close enough to negotiate confidently.
Frequently Asked Questions
Is furniture from the 1970s or 80s considered antique?
No — that’s vintage, not antique. True antique status requires the piece to be at least 100 years old, so furniture from the 70s and 80s won’t cross that line for another few decades.
Does refinishing ruin an antique’s value?
Often, yes. Collectors typically pay a premium for original finish, even with some wear, over a piece that’s been stripped and refinished. If you’re unsure whether to refinish something, it’s worth researching the specific piece first.
What’s the easiest way to spot a reproduction?
Check the screws and the joinery first — those are the hardest details to fake convincingly, and they’re usually the fastest giveaway on a reproduction trying to look older than it is.
