How to Tell If Something Is Antique: 12 Signs of Real Age
Learn how to tell if something is antique: wear patterns, hand tools, screws and nails, marks, materials and the red flags that point to a reproduction.

An "antique" is generally an item at least 100 years old. "Vintage" usually means at least 20–30 years old. But how do you tell, standing in a shop or an attic, whether something really is that old? Age leaves clues. Here are the ones experts check first.
1. Natural, logical wear
Real age shows wear exactly where hands and feet touched it for decades: chair arms, drawer edges, the base of a vase, handles. Fake "distressing" is often evenly spread or in places nobody would touch.
2. Hand tool marks
Before mass production, craftsmen left irregular marks: slightly uneven dovetails, plane marks on the underside of tables, saw marks that aren't perfectly straight. Perfect uniformity suggests machines and later manufacture.
3. Dovetail joints
Hand-cut dovetails are few, wide and slightly irregular. Machine-cut dovetails are many, narrow and identical. See dovetail joints for dating furniture.
4. Screws and nails
Old screws are hand-filed with off-center slots and irregular threads. Phillips-head screws appear much later. Square, hand-forged nails point to earlier pieces; uniform round wire nails to later ones.
5. Shrinkage
Wood shrinks across the grain over time, so round tabletops become slightly oval and panels may show gaps. A perfectly round, centuries-old tabletop is suspicious.
6. Oxidation and patina
Unfinished wood darkens on exposed surfaces over time, while protected surfaces stay lighter. Metals develop patina; old brass and bronze darken evenly. Fresh wood inside a "Georgian" drawer is a warning sign.
7. Marks and their wording
On pottery and porcelain, the wording matters. "Made in England" or "Made in Japan" generally indicates later manufacture; marks with "Ltd" also point to later dates. Read more in pottery marks identification.
8. Materials
Plastics, modern plywood, staples, and synthetic fabrics all postdate genuine antiques of most styles. Check hidden areas: the backs of cabinets, the undersides of seats.
9. Weight and feel
Old porcelain, crystal and solid wood tend to feel heavier and denser than modern copies. Cast reproductions of metalwork can feel rough or grainy.
10. Hardware
Original handles leave a single set of holes. Extra filled holes mean hardware has been changed — not proof of age either way, but important for value.
11. Style consistency
Every element should fit one period. A Victorian body with Art Deco hardware has been altered. Learn period styles in antique periods timeline.
12. Provenance
Old receipts, photographs, auction labels and family history can support age claims. Keep them with the object.
Red flags for reproductions
- Even, all-over "aging"
- Dirt that wipes off easily but nothing underneath
- Too-perfect symmetry and finish
- Marks that look stamped on rather than fired in
- A price that seems too good

Frequently asked questions
How old does something have to be to be an antique?
The common definition is at least 100 years old. "Vintage" usually means 20 years or more but under 100.
Is something valuable just because it's antique?
No. Many antiques are common and affordable. Rarity, condition, maker and demand drive value.
What is the fastest way to check age?
Look at construction (joints, screws, tool marks) and marks. An app scan can give an estimated era to guide your checks.
