Antique Buttons: How to Identify Valuable Civil War and Fashion Buttons

Valuable antique buttons are identified by their material (Bakelite, Celluloid, Jet), shank construction, and specific backmarks. Civil War buttons (1861–1865) must be authenticated by checking the rear for period-correct maker marks like Scovill or Horstmann. Genuine fashion buttons often feature intricate carving and lack the molded seams found on modern plastic reproductions.

Imagine you are at a dusty estate sale in rural Pennsylvania, sifting through a rusty biscuit tin filled with tangled thread and notions.

Your fingers brush against a heavy, dull brass disc featuring an eagle, or perhaps a deeply carved, cherry-juice colored piece of plastic.

Most people see junk. But you might be holding a Civil War infantry button worth $150, or a rare Bakelite pictorial sought after by the high-end collector market.

Knowing what to look for changes everything.

How Can I Distinguish Civil War Buttons From Modern Replicas?

The most critical factor in authentication for military buttons is the “backmark.”

During the 1860s, manufacturers stamped their names on the back of the button. Common authentic names include Scovill Mfg Co, Waterbury Button Co, and Horstmann & Bros.

If the back is blank or says “Made in Taiwan,” it is a modern reproduction.

Another clue is the construction. Most Civil War buttons are three-piece construction: a face, a back, and a rim holding them together.

You must also check the provenance if possible. A button dug from a known battle site carries a different historical weight than one found in a sewing box, though both can be genuine.

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

What Materials Are Most Valuable in Fashion Buttons?

For non-military buttons, material is king. The fair market value often depends on whether the button is early plastic or natural material.

Bakelite (1907–1940s) is highly collectible. These buttons have no seams and make a distinct “clunk” sound when tapped together.

To test for Bakelite without damaging the item (a key part of conservation), rub the button with your thumb until warm and smell it. It should smell like formaldehyde.

Victorian Black Glass (Jet) buttons from the late 19th century are often confused with black plastic. Real Jet is actually fossilized coal and feels warm to the touch, whereas “French Jet” is black glass and feels cold.

When assessing glass buttons, the technique is similar to what we cover in our guide on Identifying Antique Perfume Bottles: From Commercial to Art Glass, specifically regarding glass quality and mold marks.

How Do Shank Styles Help Determine Age?

The shank (the loop on the back) is often more telling than the face of the button.

Birdcage Shanks: Common on 18th and early 19th-century metal buttons. They look like a raised cone of metal bars.

Self-Shanks: Common on Bakelite and Lucite. The shank is drilled directly into the back of the button material itself.

If you see a glued-on metal plate, that is a major red flag for forgery detection. Antique buttons rarely used glue; components were soldered or mechanically crimped.

Correct attribution of the shank style can date a piece within a 10-year window.

What Is the Current Market Value for Rare Buttons?

Value varies wildly based on the condition report.

A standard “poke box” button might be worth $1–$3. However, a “Habitat” button (clear Lucite with insects or moss embedded inside) can fetch $50–$100 at an auction house.

Arita Porcelain buttons from Japan, hand-painted with intricate scenes, are also premium items.

Be wary of “button sickness.” This occurs when early celluloid buttons begin to degrade, off-gassing nitric acid that can rust nearby metal buttons.

If you find a crumbling button in a lot, remove it immediately to protect the replacement value of the rest of the collection.

Always check auction estimates from reputable dealers rather than eBay asking prices to get a realistic sense of worth.
