<span>Why Button Identification Matters</span>

</h2>

<div class="section-header__body">Understanding how to properly identify and date buttons provides crucial context for collectors, historians, archaeologists, and fashion enthusiasts.</div>

Button identification isn’t just about satisfying curiosity – it’s fundamental to understanding their historical and monetary value. As noted by Agnes’ Vintage World, “Button identification is crucial to its dating. The state of the buttons can be misleading, as the colour can be very well preserved.” Without proper identification skills, you might miss a rare treasure or misattribute a button’s age and significance.

Accurate identification allows you to:

  1. Determine appropriate conservation methods
  2. Authenticate period clothing and artifacts
  3. Establish fair market values for buying, selling, or insurance
  4. Contribute to historical research and documentation
  5. Create more meaningful and valuable collections

For metal detectorists, button identification can provide critical dating evidence for archaeological sites. According to the Friendly Metal Detecting Forum, “There are some websites that link to some old button manufacturers info can be found online” that can help place buttons in their proper historical context.

<span>Identifying Button Materials</span>

</h2>

<div class="section-header__body">The material of a button is often the first clue to its age, origin, and value. Different materials were popular during specific historical periods.</div>

Metal Buttons

Metal buttons have been produced for centuries, with materials ranging from precious metals to alloys. Here’s how to identify common metal button types:

Brass Buttons: Popular from the 18th to early 20th centuries, especially for military and uniform buttons. Early brass buttons often have a warmer, more golden tone than modern examples. According to HobbyLark, “One way is to look at the material in or around the shank or buttonholes. You can sometimes see unprocessed materials in or around these holes.”

Copper Buttons: Often used for utilitarian purposes, these buttons develop a distinctive green patina over time.

Silver and Gold Buttons: Typically found on high-end garments and can be hallmarked. Look for quality marks or stamps indicating silver content (sterling, 800, 925, etc.).

Pewter Buttons: Common in the 18th and early 19th centuries, these soft metal buttons have a dull gray appearance and often show significant wear.

Shell Buttons

Mother of Pearl: These iridescent buttons made from mollusk shells have been popular since the 18th century and remain desirable today. As noted in the research on identifying vintage mother of pearl buttons, “Mother of pearl buttons have more depth of color than plastic buttons. It takes a look to tell them from any other buttons due to their noble opalescent sheen.”

Pearl Shell: Similar to mother of pearl but with less iridescence.

Abalone: Features distinctive blue-green-purple shimmer.

Natural Material Buttons

Bone and Horn: Used since ancient times, these buttons can be distinguished by their natural grain patterns and warm coloration.

Vegetable Ivory (Tagua Nut): Popular in the late 19th and early 20th centuries, these plant-based buttons resemble ivory but are more sustainable.

Wood: Varies widely in appearance based on the type of wood used and any applied finishes.

Early Synthetic Materials

Bakelite: The first fully synthetic plastic, popular from the 1920s-1940s. According to Va-Voom Vintage, you can identify Bakelite by warming it with friction: “Rub the piece with your thumb until it becomes warm and give it a sniff. If it is Bakelite, it will give off the chemical scent of formaldehyde.”

Celluloid: An early plastic used from the 1870s to the 1930s that can become brittle and yellowed with age.

Lucite: A clearer acrylic plastic popular from the 1940s onward.

Casein (Galalith): A milk-based plastic popular in Art Deco designs from the 1900s-1930s.

Ceramic and Glass Buttons

Porcelain/China: Often hand-painted with delicate designs, popular in the 19th century.

Prosser Buttons: Machine-made ceramic buttons with a distinctive seam around the edge and often a dimpled back. According to the DAACS Cataloging Manual, Prosser buttons “Generally date after 1840.”

Glass: Available in various colors and styles, from simple utilitarian buttons to elaborate Victorian designs.

<span>Dating Buttons by Construction Methods</span>

</h2>

<div class="section-header__body">The way a button is manufactured provides crucial clues about its age and origin.</div>

Button Shanks and Attachments

The shank (attachment method) of a button is one of the most reliable indicators of its age. According to Scott Clark’s dating guide, button shanks evolved significantly over time:

Alpha-style shank: Cast as part of the button, used primarily before 1800.

Omega-style shank: Wire loop shaped like the Greek letter omega, common from approximately 1800-1860.

Eye and wire shank: Wire shank inserted through an eye cast as part of the button, used mid-19th century.

Sanders-type shank: Self-shank with a bar across the back, popular in the late 19th century.

Sew-through buttons: These have holes rather than shanks and their pattern (2-hole or 4-hole) and spacing can help with dating.

Manufacturing Techniques

Hand-crafted buttons: Look for slight irregularities in shape, inconsistent thickness, or uneven hole placement. As noted by LoveToKnow, antique buttons often “show signs of being handmade, such as a lack of uniformity.”

Die-struck buttons: Common in military and uniform buttons from the early 19th century onward.

Molded buttons: Became increasingly common with the advent of plastic materials in the late 19th and early 20th centuries.

Fabric-covered buttons: The construction of the back and the covering method can indicate age.

Prosser process: Used for ceramic buttons after 1840, creating a distinctive “china” button with a slightly pitted bottom surface.
