Brass military or uniform button with central hole, likely early 20th century

This appears to be a vintage military or uniform button, commonly used on American military uniforms or civilian service uniforms from the late 19th to early 20th century. Such buttons were typically made of brass or gilt metal and featured various insignia or plain designs depending on the branch of service or organization. The central shank hole indicates it was sewn onto fabric rather than having a loop attachment. Military buttons and uniform accessories are highly collectible among militaria enthusiasts, historians, and metal detecting hobbyists. These items appeal to collectors interested in American military history, particularly those focusing on specific conflicts like the Spanish-American War, World War I, or the Indian Wars period. The buttons serve as tangible connections to the past and are valued for their historical significance, craftsmanship, and the stories they represent about the individuals who wore them.
