Bronze USMC Officer Collar Eagle, Globe, and Anchor (EGA) insignia, circa WWII era

The Eagle, Globe, and Anchor (EGA) is the official emblem of the United States Marine Corps, adopted in its current form in 1868. During World War II, USMC officers wore bronze collar insignia featuring this iconic design, with separate pieces for left and right collar placement. These insignia were manufactured by various makers and featured screwback or clutch-back attachments, with wartime examples often showing variations in metal composition due to material shortages. Vintage USMC collar insignia are highly sought after by military collectors, historians, and veterans' organizations for their historical significance and connection to the Marine Corps' storied legacy. The EGA remains one of the most recognizable military emblems in the world, and authentic WWII-era examples represent an important piece of American military history. Collectors particularly value pieces with maker's marks, unusual variations, or documented provenance to specific Marine units or individuals.
