Antique Button Identification and Value Guide

Start with a three-view inspection

A useful button identification starts with three views: the front design, the back construction, and the side profile. The front tells you the motif and style period, the back may show a maker or quality mark, and the side reveals thickness, molded layers, metal crimping, or a replaced shank.

Measure the diameter in millimeters or ligne if you collect buttons seriously. Coat buttons are generally larger than cuff or vest buttons, and military buttons often appear in predictable size groups, but size alone is not a date. Note whether the button is a single, part of a matched set, or still attached to a card or garment.

• Use a 10x loupe to inspect seams, cracks, backmarks, and shank attachment.
• Do not clean before identification because polishing can remove gilt, paint, japanning, or surface patina.
• Record diameter, material guess, shank type, backmark, motif, and condition together.

Identify the material before dating the button

Material is one of the fastest clues. Mother-of-pearl has a cool feel, layered edge, and iridescent glow; bone may show tiny pores or canal lines; horn is often warm-toned and slightly translucent at thin edges; shell, bone, and horn were common on everyday clothing as well as better garments.

Glass buttons range from molded black glass and pressed pictorial examples to cut steel-like faceted designs. Metal buttons may be brass, copper alloy, pewter, silver, steel, or gilt over base metal. Later materials such as celluloid, Bakelite, casein, and other plastics can look antique, so avoid dating a button by color alone.

Never use a hot pin test on a potentially valuable button. It is destructive and unnecessary for most collecting decisions. Instead, examine weight, mold seams, smell only if the material is already damaged, and compare with known examples under magnification.

• Mother-of-pearl: layered, iridescent, usually drilled or sew-through on utilitarian examples.
• Horn: streaked or translucent, often molded, pressed, or carved.
• Glass: cool, hard, often molded with sharp or rounded detail depending on period and quality.
• Metal: look for plating wear, soldered shanks, crimped backs, and maker backmarks.
• Early plastics: light, molded, sometimes warped, and more common in late 19th to 20th century buttons.

Read shanks, backs, and construction clues

The shank is the loop or attachment point on the back of a button. A hand-soldered metal loop, a cast self-shank, a wire shank set into a backplate, or a sew-through drilled construction can all help narrow the type and period, but no shank style gives an exact date by itself.

Two-piece metal buttons often have a front shell joined to a backplate, sometimes with a crimped edge. One-piece buttons may be cast, stamped, or molded as a single body. Repairs are common: an old front can have a later replacement shank, and a military button can be dug, flattened, rebacked, or artificially aged.

Back texture matters. Smooth backs, depressed backs, tin backs, japanned backs, and gilt backs appear on different button types. Look for tool marks and manufacturing consistency; modern reproductions may have overly crisp casting, incorrect shank style, or backmarks that do not match the claimed period.

• Self-shank: part of the button body, common on molded and cast examples.
• Wire shank: may be inserted, looped, or anchored into a backplate.
• Soldered shank: often seen on metal buttons, but solder repairs can confuse dating.
• Sew-through holes: common on utility buttons, shell buttons, bone buttons, and later mass-produced examples.

Decode maker marks and backmarks carefully

Backmarks can identify a manufacturer, retailer, quality grade, city, or patent reference. Names such as Scovill, Waterbury, Firmin, and other button makers appear on many collectible metal and uniform buttons, but the wording, punctuation, and layout must be compared with reliable references before assigning a date.

Terms like Extra Quality, Superior Quality, Treble Gilt, Orange Colour, or Rich Colour are not necessarily maker names. They often describe finish or trade quality. A patent date gives the earliest possible date for that feature, not proof that the button was made in that exact year.

Some civilian fashion buttons have no mark at all, especially glass, shell, bone, and fabric-covered examples. In those cases, material, construction, motif, and comparison to documented examples are more useful than trying to force a maker attribution.

• Photograph backmarks straight-on and at an angle to catch faint lettering.
• Transcribe punctuation exactly, including stars, dots, wreaths, and address lines.
• Treat patent dates as a starting point, not a final appraisal date.
• Be cautious with rare maker claims unless a button specialist or reference confirms them.

Military, livery, and uniform buttons

Military button identification begins with the device on the front: eagle, crown, anchor, artillery cannon, infantry number, state seal, regiment number, or branch symbol. Then compare the backmark, shank, size, and construction to known military button references. A design may have been used for decades, so front design alone is rarely enough.

United States military buttons often include general service eagles, state militia motifs, and branch-specific symbols. British and European examples may show crowns, regimental numbers, crests, or monograms. Naval buttons commonly use anchors, but commercial, yacht club, and shipping-line buttons can imitate naval styling.

Livery buttons are frequently mistaken for military buttons. They may show family crests, initials, animals, coronets, or heraldic designs and were worn by servants or staff. A heraldic crest does not automatically mean royal or military origin, and rare family attribution usually requires specialist research.

• Confirm whether the symbol is military, civic, fraternal, transportation, police, fire service, or livery.
• Compare coat-size and cuff-size versions; matched sets can be more desirable than singles.
• Dug buttons need careful evaluation because corrosion, ground action, and cleaning can reduce value.
• For rare regiment, Civil War, Revolutionary War, or early militia claims, get hands-on expert confirmation.

Value factors and realistic price ranges

Most antique buttons are affordable collectibles rather than high-value antiques. Common late 19th and early 20th century shell, bone, metal, and sew-through utility buttons may sell for only a small amount individually, especially when loose and worn. Matched sets, scarce motifs, exceptional condition, or original cards can improve desirability.

Decorative Victorian glass, picture buttons, enamel buttons, cut steel, high-quality metal pictorials, early plastics with strong designs, and unusual materials can bring stronger prices. Many better single collectible buttons trade broadly in the low tens of dollars, while scarce or exceptional examples may sell higher depending on competition and documentation.

Military buttons have the widest range. Common uniform buttons may remain modest, while confirmed rare regiment, early state militia, named maker, or historically important examples can reach much higher auction results. Because reproductions and misidentifications are common, valuable military buttons should be assessed by a militaria or button specialist before sale or insurance.

• Lower value: common utility buttons, heavy wear, missing shanks, corrosion, or mixed craft lots.
• Moderate value: attractive Victorian glass, clean metal pictorials, good livery buttons, and matched sets.
• Higher value potential: rare military, early dated backmarks, exceptional enamel, unusual materials, and documented scarce designs.
• Value depends on recent comparable sales, not asking prices alone.

Condition, cleaning, and storage

Condition is critical because small damage can dominate a button’s value. Check for chips on glass, cracks in shell, insect damage in horn or bone, verdigris on copper alloys, missing paint, loose backplates, bent shanks, and over-polished gilt. A button with an original surface is usually preferable to one made shiny by aggressive cleaning.

Avoid soaking mixed-material buttons. Water can loosen fabric, rust steel backs, lift paint, or swell organic materials. For most buttons, a dry soft brush, gentle dusting, and separate storage are safer than chemical cleaning.

Store buttons in acid-free trays, archival envelopes, or compartment boxes. Keep celluloid away from heat and direct sunlight, separate corroding metal buttons from shell and fabric examples, and label uncertain identifications as tentative so future research does not inherit a guess as fact.

• Do not polish gilt military buttons unless a specialist recommends it.
• Keep buttons with unstable verdigris away from other buttons.
• Store sets together and preserve original cards or garment context when possible.
• Use reversible labels and avoid glue, tape, or permanent marker on button surfaces.
