What Is an Antique? Why Age, Rarity, and Value Matters

The antique market fluctuates as trends change. Things that sold for thousands of dollars a decade ago might only be worth a few hundred today. In addition, the items that people considered vintage twenty years ago are now marketed as full-fledged antiques.

But how old does an object have to be to be regarded as an antique? Generally, an item must be at least 100 years old to qualify as an antique, following a widely accepted benchmark used by collectors and dealers. Here’s a quick breakdown of other key definitions and exceptions.

How Old Are Antiques?

The Smoot-Hawley Tariff Act of 1930 defined antiques as items produced before 1830 to distinguish genuine antiques from mass-produced items.¹ This law was one of the first to universally recognize antiques as at least 100 years old. However, this categorization can vary depending on the item. Most antique dealers think any century-old item, like a simple and inexpensive door hinge, would qualify as antique. In this context, a century-old rusty nail would be called an antique.

However, some argue that functional items like early industrial tools or utilitarian household items—for example, a century-old cast iron skillet—may not hold the same appeal or recognition as antiques in traditional collecting circles. In general, an item’s value and historical significance do not impact whether it can be called an antique. However, some upscale antique dealers think an antique should have a relatively stable (and high) market value.

In this case, only some century-old items would qualify. For instance, a Louis XVI giltwood armchair or a Georgian silver tea set might meet these criteria due to their historical significance and consistent demand among collectors. On the other hand, these dealers would label inexpensive knick-knacks as collectibles (not antiques), even if they were over 100 years old.

Age of Vintage Items

The term vintage is used more loosely than antique. Anything that shows a little age can be called vintage, whether a 15-year-old tablecloth or a 60-year-old teapot. However, commonly accepted standards often define vintage items as being at least 20 years old.

Exceptions

Some dealers think anything over 50 years old should be considered antique, but this is less common (and the term might be used to try to make an item seem more important than it is). Usually, these newer pieces would be labeled as either vintage or collectible.

However, some niches have more defined terms that make qualifying an antique less of a gray area. For instance, according to the Antique Automobile Club of America, an antique car is any car over 25 years old.

Another exception is heirloom jewelry, where anything less than 40 years old is considered estate and should not be called vintage or antique. (Vintage jewelry is any item between 40-99 years old.) Here’s a timeline to help you visualize the exceptions.

History of Antiques

Antique collecting has been popular since ancient times. In fact, some believe that the first pieces of collected art were found in tombs dating back to 5000 BC, a claim supported by archaeological evidence of decorated pottery and carved items from that era.² These early works of art were painted on pottery, stone, metal, ivory, wood, and other materials and kept for seemingly sentimental reasons.

For contemporary collecting, you’ll find antiques from several design periods, including:

• Victorian: 1837-1901
• Arts and Crafts: 1895-1915
• Art Nouveau: 1890-1910
• Art Deco: 1920-1935

Retro and Modern design eras come next, but items from these eras are usually considered vintage (not antique) because they lack the age threshold of 100 years that is widely accepted for antiques. For example, a 1950s Eames lounge chair or a 1970s lava lamp might be sought after by collectors but would still fall under the vintage category due to their relatively modern production dates. Additionally, these items often feature materials and production techniques that are characteristic of modern manufacturing, differentiating them from true antiques.

Do Antique Stores Only Sell Antiques?

When you go into a typical antique shop, you’ll likely find things from all eras and price ranges. Not everything in the shop is technically an antique—and you may even find some antique reproductions. However, this variety might not be the case in a high-end antique shop, which only carries antiques of a particular era or quality.

For example, antique malls usually don’t have requirements when it comes to the exact age and quality of items. You’re much more likely to score a deal by finding something where a dealer “doesn’t know what they have.” A high-end online site like 1stdibs has many restrictions to ensure only top-quality antiques are listed. These items would have to be old, collectible, and valuable.

Identifying Reproductions

Reproductions are often distinguished by their materials and craftsmanship. For example, machine-cut dovetail joints in furniture or perfectly uniform tool marks can signal a reproduction, whereas authentic antiques typically feature hand-crafted irregularities.

Additionally, reproductions may use modern materials like synthetic finishes, which were unavailable in historical periods. These steps are especially helpful for distinguishing reproductions from genuine antiques or verifying an item’s authenticity.

Look for Marks or Labels

Many antique items, especially furniture, pottery, and silver, may have maker’s marks, hallmarks, or labels that can provide clues about their age. These marks might include the manufacturer’s name, location, or a specific date. You might need a magnifying glass to see small marks. There are reference books and online databases that can help you decipher these marks and understand what they mean. If a pottery reference does not identify the stamp, compare it with additional manufacturers and mark types in this antique maker’s marks directory. Even a simple label indicating the country of origin can help you narrow down the time frame, as labeling laws have changed over the years.

Check the Materials

The materials used in an item can be a significant clue to its age. For example, certain types of wood, glass, or metal might have been popular during specific periods. Bakelite, for instance, was a common plastic used in the early 20th century. If you find a piece made of Bakelite, it’s likely from that era. Understanding the types of materials used in different time periods requires some research, but there are many resources available, including books, websites, and even museum exhibits, that can help you learn about historical materials.

Feel the Weight and Craftsmanship

Older items often exhibit signs of hand craftsmanship that are different from machine-made pieces. For example, hand-cut dovetail joints in furniture might be slightly uneven, whereas machine-cut ones are perfectly symmetrical. The weight of an item can also be a clue. Older glass and silver items might feel heavier (or, in some cases, lighter) than modern reproductions. Feeling the surface for tool marks, chisel cuts, or other signs of handwork can provide insights into the age.

To illustrate these steps in practice, here’s how you’d evaluate an early 20th-century piece of silverware:

1. Examine the back of a silver spoon for a hallmark. You might find a stamp indicating it was made by Gorham in the 1920s, providing an approximate time frame and metal composition.
2. Notice the tarnish on the spoon. The spoon’s material, sterling silver (which was confirmed by the hallmark), was widely used during that period, and its tarnish patterns can signal its authenticity.
3. Feel the spoon’s weight and examine the details. The spoon’s weight and the hand-chased floral patterns indicate a level of craftsmanship typical of its era.
