ANCIENT ORDER Of HIBERNIANS AOH IRISH BRIGADE CIVIL WAR BUTTON 14mm DazzleCity

Beautifully detailed with shamrocks - cuff button emblazoned with the symbol for the Ancient Order of Hibernians. Size is 14mm. I think that it was manufactured in the 1860's. Civil War Era just under 1" across. I've made no attempt to clean it because I'm not sure about cleaning something this old.
