RARE Authentic Civil War Union 69th NY Irish Brigade "Harp of Erin" Kepi Badge Insignia Relic

This is an exceptionally rare and historically significant artifact: an authentic Civil War-era Union Irish Brigade cap badge. Measuring approximately 2 inches in height, this insignia features the traditional Irish harp surmounted by a winged female bust (the Goddess Eire). These badges were privately purchased and worn proudly by members of the Irish Brigade as an identity item and a symbol of their heritage and allegiance. They were a vital part of the Irish-American identity during the war, particularly for regiments like the "Fighting 69th" New York Infantry, known for their green battle flags and Gaelic war cry, “fág an bealach!” or “Clear The Way!”. This insignia's aged patina and condition are consistent with a genuine 19th-century artifact, often recovered from battlefields or veteran estates.
