I found this button yesterday at a site that has produced coins dating from 1829 to 1845. There have also been confederate buttons dug here. My question is if this is a military cuff button or a civilian button? I've never seen one like the one I just dug. Any information about it would be great! Age, value, (If any) and if it is rare. The back of the button is marked "Scovills Super Fine"
