How to Identify and Date Antique Furniture
Read joinery, hardware, wood, and tool marks to date a piece of furniture and tell genuine antiques from later reproductions.
Published March 26, 2026
Furniture rarely carries an obvious label, so dating it means reading how it was built. The good news is that construction techniques changed in predictable ways over the centuries, and those changes leave clues you can learn to see. Work from the inside out, examining drawers, backs, and undersides where the maker left the honest evidence.
Read the Joinery and Tool Marks
Pull a drawer and study the joints. Hand-cut dovetails are few, uneven, and slightly irregular, while machine-cut dovetails after the 1860s are uniform and closely spaced. Saw marks tell the same story: straight, parallel marks suggest a hand or sash saw, while regular arcs reveal a circular saw used from the mid-1800s onward.
- Look for honest, irregular hand-cut dovetails on early case pieces.
- Check secondary woods inside drawers, which makers chose by region and era.
- Feel for slight unevenness from hand planing versus perfectly flat machined surfaces.
Inspect Hardware, Wood, and Patina
Original hardware leaves a tell-tale shadow and a single set of screw holes; extra holes mean the pulls were swapped. Hand-forged or early machine-cut screws have off-center, irregular slots, while modern Phillips screws signal a later repair. Genuine patina is the soft, uneven glow of decades of handling and light, deepest where hands and sleeves touched, and it cannot be convincingly faked overnight.
- Confirm the back boards show age, oxidation, and consistent shrinkage.
- Verify the wood species and finish match the claimed period.
- Treat a flawless, uniform finish on an old form with healthy suspicion.
Confirm With Marks and Comparison
Some makers stamped or labeled their work; check the back, the underside of a top, and inside drawers for branded marks, paper labels, or stencils. Match what you find against documented examples from the same maker before trusting it. When the evidence all points the same way, you can date and value the piece with real confidence rather than guesswork.
Frequently Asked Questions
How can I tell if a piece of furniture is genuinely antique? +
Examine the joinery, saw marks, hardware, and secondary woods rather than the seller's claim. Hand-cut dovetails, irregular screw slots, oxidized back boards, and honest patina all point to age, and when several of these agree you can date the piece reliably.
Are old dressers worth anything? +
It depends on maker, period, originality, and condition. A solid-wood dresser with original finish, hardware, and clean lines from a sought-after era can hold real value, while a refinished or heavily repaired piece usually sells for far less.
Does refinishing antique furniture reduce its value? +
Often yes, because collectors prize original surface and patina. Stabilize and clean gently, but confirm a finish is not the original before you strip it, since refinishing can erase a large share of a piece's value.
