United States Marine Corps Eagle, Globe, and Anchor (EGA) Insignia

This item is a United States Marine Corps Eagle, Globe, and Anchor (EGA) insignia, specifically an enlisted dress or service cover ornament. The piece is constructed from metal with a blackened or dark bronze finish, which is characteristic of field or service uniform variants from the early to mid-20th century. Physically, the item features an eagle with spread wings perched atop a globe showing the Western Hemisphere, with a fouled anchor positioned behind the globe. The casting displays significant detail in the feathers of the eagle and the continents on the globe, although some of this detail has been softened by age and surface wear. Notable features include the traditional 'fouled anchor' with a visible rope coiled around it. Regarding condition, there is a visible dark patina across the entire surface, suggesting significant age. There is mild surface abrasion and some thinning of the darkened finish on high-relief areas like the eagle's head and the center of the globe, revealing a hint of the underlying copper-alloy metal. Based on the style and finish, this appears to be a World War II era or shortly thereafter (M1937 pattern) insignia. The craftsmanship is of standard military issue quality for the period, utilizing a screw-post or pin-back mounting system (obverse view only). The lack of high-gloss gold plating suggests it was intended for utility or service uniforms rather than formal dress blues.
