The 10 Most Commonly Faked Antiques and How to Spot Them

The most commonly faked antiques include Tiffany lamps, Staffordshire dogs, cast iron banks, and Roseville pottery. Authentic pieces exhibit natural patina, crisp maker’s marks, and period-correct hardware, whereas modern reproductions often feature artificial aging, Phillips-head screws (invented in 1932), and sloppy paint application under blacklight inspection.

Imagine you are at a dusty estate sale in rural Pennsylvania, and you spot what looks like a pristine 19th-century mechanical bank. Your heart races, but before you hand over your cash, you need to be absolutely certain it isn’t a modern reproduction designed to fool eager buyers in today’s collector market.

As a certified appraiser with over 20 years in the field, I’ve seen countless buyers burned by clever fakes. Let’s break down the telltale signs of the most forged items so you can buy with confidence.

How can I tell if my antique cast iron bank is a real original?

Mechanical cast iron banks from the late 1800s are heavily reproduced. Original manufacturers like J. & E. Stevens used tight molds, resulting in smooth surfaces and perfectly aligned joints.

A major red flag for forgery detection is the hardware. If you see a Phillips-head screw holding the bank together, it is a post-1930s reproduction. Authentic banks use flat-head screws or pins. Furthermore, genuine 19th-century paint will show a natural, uneven wear pattern, not uniform “distressing” applied by a modern factory.

Identifying these marks manually can take hours. Using the Antique Identifier app, you can simply take a photo and get an instant result.

What are the secret markings located on genuine Tiffany Studios lamps?

A true Tiffany Studios lamp commands a massive auction estimate, often reaching tens of thousands of dollars. Fakers know this. When evaluating a leaded glass shade, tap the glass lightly with your fingernail; authentic Tiffany glass is set tightly in copper foil and will sound dull, while fakes often rattle.

Authentication also relies heavily on the bronze base. Genuine Tiffany bases from the 1900-1920 period develop a rich, greenish-brown patina over time. If a base looks painted or feels suspiciously lightweight, walk away. Always check the maker’s mark stamped on the bottom for correct font spacing and the specific serial numbers used during the studio’s operational years.

How do I spot a fake Staffordshire dog figurine?

Those iconic ceramic spaniels that sat on Victorian mantels are notorious for being reproduced. An authentic 19th-century Staffordshire dog will always have a small vent hole on the base or back, roughly the size of a dime. This allowed steam to escape in the kiln.

Modern fakes often have a smooth, completely glazed base with a perfectly round, machine-cut hole. When seeking an accurate appraisal or condition report, an expert will also check the painted details. Originals feature fine, single-stroke brushwork on the facial features, while reproductions often look airbrushed or cartoonish.

Are there reliable ways to authenticate Roseville pottery?

Roseville pottery, particularly patterns like Pine Cone and Magnolia from the 1930s and 1940s, is widely copied. The most critical step in evaluating Roseville is examining the glaze. Genuine pieces have a matte, blended glaze that transitions smoothly between colors.

Fakes from overseas usually have a shiny, harsh glaze and muddy details. Pay close attention to the raised “Roseville U.S.A.” mark on the bottom. An authentic mark is crisp and easy to read. This technique is similar to what we cover in our guide on Identifying Antique Perfume Bottles: From Commercial to Art Glass.

How do you verify the age of Shaker furniture?

True Shaker furniture is prized for its minimalist design and incredible craftsmanship. Because of its high fair market value, reproductions are everywhere. You must look at the joinery. Authentic 19th-century pieces use hand-cut dovetails that are narrow and irregular.

If the drawer joints are perfectly uniform, they were machine-cut in a modern factory. Solid provenance—a documented trail of ownership—is often required by any reputable auction house before they will accept a high-end Shaker piece for sale.

What should I look for when evaluating antique Jadeite?

Original Fire-King and McKee jadeite glassware from the 1940s and 1950s has a distinct, glowing sea-green color. Reproductions often look too pale, too dark, or somewhat translucent.

When you take a piece to an antique dealer, they will look for the manufacturer’s mark embossed on the bottom. However, keep in mind that many genuine mid-century pieces were unmarked. You must learn the specific mold shapes and weight of genuine pieces to master proper attribution.

How can I test Civil War memorabilia for authenticity?

Faked military antiques are incredibly common. From belt buckles to swords, the market is flooded with aged reproductions. To confirm authenticity, you must understand the materials of the 1860s.

For brass items, heavy green verdigris can be artificially induced with chemicals. Authentic patina takes over a century to form and is hard and crusty, not soft or powdery. If an item looks too good to be true, it likely requires professional conservation analysis to determine if it is a genuine artifact.

What are the signs of reproduction Meissen porcelain?

Meissen porcelain has used its famous crossed-swords mark since 1720. Naturally, this mark has been forged for centuries.

To establish the replacement value of a genuine piece, look closely at how the mark is applied. Authentic Meissen marks are painted by hand in cobalt blue under the glaze. If the swords look stamped, sit on top of the glaze, or the porcelain itself is thick and heavy, you are holding a fake.

How do you detect fake cast iron doorstops?

Like mechanical banks, cast iron doorstops from makers like Hubley are prime targets for reproduction. A genuine 1920s Hubley doorstop will have tight seams and a smooth front and back.

Pro Tips for Doorstops:

• Check the seams: Fakes have wide, sloppy gaps between the front and back halves.

• Feel the surface: Modern reproductions are cast in rough sand, leaving a pitted, sandpaper-like texture.

• Inspect the paint: If a piece looks newly painted, it may hide a modern casting. Always check for signs of poor restoration.

Are reproduction Depression glass pieces easy to spot?

Yes, if you know what to look for. Patterns like Cherry Blossom and Madrid were heavily reproduced in the 1970s and 1980s.

Genuine Depression glass from the 1930s is thin, delicate, and often contains small straw marks or tiny bubbles from the manufacturing process. Reproductions tend to be thick, heavy, and lack the fine detailing in the molded patterns. Always run your finger along the edges; authentic pieces have smooth, fire-polished rims, while fakes can feel sharp.
