WW2 US USMC Screw Back Collar Insignia Badge Single

The WW2 US USMC Screw Back Collar Insignia Badge Single is an original military artifact from the United States Marine Corps dating to the Second World War. This single collar insignia features the traditional USMC emblem, typically consisting of an eagle, globe, and anchor, cast in metal and finished to military specifications of the era. The screw back attachment mechanism, used before the widespread adoption of clutch backs, allowed the badge to be securely fastened to the uniform collar and easily removed for cleaning or transfer. Such insignia served as identification and symbolized the wearer’s affiliation and rank within the Marine Corps. Single insignia badges like this were issued as part of official dress uniforms and would have been worn by enlisted personnel or officers, depending on the specific design and dimensions. Pieces of this type are relevant for collectors focusing on American military history and insignia from World War II.
