This is a circular brass uniform button featuring the 'Great Seal' of the United States, typically utilized by the U.S. Army on Service Union dress uniforms. The button is constructed from two pieces of metal (a front shell and a back plate) with a brass or gold-toned finish. The central relief depicts an eagle with wings outspread, clutching an olive branch and arrows, with a shield on its chest and an arc of thirteen stars above. The eagle's head is turned to its right. Physically, the button appears to be roughly 15mm to 20mm in diameter. The surface shows a significant aged patina with darkening in the recessed areas of the design, which is characteristic of genuine vintage or antique military hardware. There is minor surface wear and small scratches consistent with use and age, but the high-relief details remain sharp and legible. This specific design pattern was adopted in 1902 and remains in use, though the craftsmanship and materials suggest a mid-20th-century production, likely from the WWII to Korean War era. The craftsmanship is high-quality, typical of government-contracted military regalia.

Based on my visual examination of this U.S. Army Great Seal uniform button, I find it to be a genuine mid-20th-century specimen, likely dating from the World War II to Korean War era. The two-piece construction and sharp relief of the 'Great Seal'—adopted in 1902—are consistent with government-contracted manufacturing standards of that period. The condition is graded as 'Good' to 'Very Good' for surplus hardware; while the brass shows a heavy aged patina and oxidative darkening in the recesses, the structural integrity remains sound and the detail in the eagle's crest and shield is well-preserved. From a market perspective, these buttons are extremely common. Millions were produced for service members, and as such, they are not considered rare. They are frequently sold in bulk or as individual replacement parts for reenactors and collectors of militaria. Factors limiting the value include the lack of a visible maker's mark (backmark) and the absence of a specific historical provenance. Higher values in this category are reserved for 19th-century variants or those with identifiable manufacturer strikes like 'Scovill' or 'Waterbury.' It is important to note that a definitive authentication cannot be completed via digital imagery alone. A physical inspection would be required to verify the metallurgical composition and to examine the backmark for specific dating. Scientific testing for gold-wash thickness or documentation linking the button to a specific decorated veteran’s uniform could marginally increase its collector interest, though it remains primarily a low-cost historical artifact.
