Looking for info, is it State Militia? Civil War?

The Missouri State Seal button is a fascinating collectible, often sparking questions about its origin and historical context. Given the OCR content mentioning "Missouri State Seal Button World War 1?", there seems to be some confusion about the button's time period — whether it is from the Civil War era or related to state militia uniforms used during World War I. Missouri has a rich military history, especially noted during the Civil War when it was a border state with both Union and Confederate forces. State Militia units were active in this period, often marked by distinctive insignia such as seal buttons bearing the state emblem. These buttons typically featured the Missouri state seal, which includes imagery like two grizzly bears flanking a shield with various symbols representing the state's heritage. However, similar buttons were also used later during World War I, as state militias evolved into National Guard units and continued using state seals on their uniforms. Identifying the exact era requires close examination of the button's style, materials, and manufacturing marks. For instance, Civil War buttons were commonly made of brass and might show different construction techniques compared to World War I-era buttons. Collectors and historians often reference detailed button catalogs or consult with experts to authenticate such items. Comparing the button to verified museum pieces or documented examples can also help clarify its origin. Understanding the context of Missouri's military insignia provides valuable insight into the state's role in American history. Whether you own such a button or simply seek information, recognizing the distinguishing features of Civil War versus World War I Missouri State Seal buttons enriches your appreciation of these historical artifacts and their stories within state militia and broader U.S. military history.
