US Uniform Buttons
US Military Uniform Button IdentificationA uniform button's use and age is principally determined by three characteristics, usually considered together. First the "device" (design) identifies the service or state militia that used it, and generally when it was used. Keep in mind that certain devices were used for many decades, so other clues are needed. The buttons construction also offers a guide to age. Finally, the backmark may not only indicate the manufacturer, but if a particular mark or the manufacturer was in existence for a narrow time period, you can further pin down the likely age and use of a button.
Some rules of thumb of age can be made as to how the shank is attached. A one-piece button with a brazed shank (soldered appearance) is a design common in the 18th century, but was also made after. A two-piece button with a brazed shank is typical of 19th century. Two pieces crimped together were first made about 1813. Two-piece hollow rounded buttons held together by a thin rim ("staff" buttons) were invented in the 1830s and used until 1902. Civil War era buttons may show a circular depression at the base around the shank. Shanks inset into holes in the button is typical after World War I. Tinned Iron Back (TIB) and stamped brass turret back buttons are common from the 1880s to 1920s. Sometimes one of the best indicators of button age is the manufacturers backmarks.
Many button manufacturers of course made non-military uniform buttons, generally called "fashion" buttons. Antique military buttons will typically have an eagle, anchor, or state seal design. Fashion buttons can have many motifs ranging from floral, scroll, or even patriotic designs that might be confused with military buttons. Sometimes private company buttons (like train companies) might be confused with military uniform buttons. Generally military uniform buttons of the Civil War era and earlier command the highest prices, and are in more demand that fashion or private company uniform buttons.
Scovill ButtonsPrior to and during the Civil War, Scovill was the most prolific button manufacturers. The Scovill name is common on buttons from the 1830 to the 1970s. The original Scovill partnerships and companies were located in Waterbury, CT, so often the name Waterbury also appears on Scovill buttons. The brothers J. M. Lamson Scovill and William Henry Scovill operated the business from 1827 to 1840. These buttons are generally marked "JML Scovill..." or "Scovills". The Scovills & Co backmark is found from around 1840 to 1850. Marks with variations of Scovill Manufacturing begin about 1850 (Scovill MG.- early 1850s, Scovill MF'G - mid 1850s). Below are some of the many Scovill backmark variations.

Backmark Acronym DefinitionsThere are a two acronyms commonly seen when button backmarks are described.
RMDC: Backmarks with a raised mark in a depressed channel. These generally date to the 1830s to 1850s.
DM: Depressed marks (the lettering looks hand stamped into the metal). These typically date to the 1860s and later.
CaveatsKeep in mind that using Scovill backmark lettering (including dots and stars) is not a foolproof method because Scovill often used old backmark dies to make newer buttons. Thus it is possible to have a World War I "Great Seal" button with an 1850 backmark. Another nuance is that while text may remain the same, other embellishments on Scovill buttons change with time. An 1850 backmark may have the name in a groove or one or two rings made of fine lines or tiny dots, whereas a later button may have no ring of dots (like the Great Seal general service button below).
Here are Scovill examples of late buttons with old backmarks that we have observed:
SCOVILL MF'G CO. WATERBURY CT. 1872-1902 (on GI 98, ring of large dots)
SCOVILL MF'G CO. * WATERBURY *: 1902-est. 1918
(on Great Seal coat buttons with ring of large dots)
