got out today & went back to one of my very 1st cellar holes.worked it slower and dug everything.aside from the few flat buttons I thought my finds of the day were the key & small buckle until i started cleaning the buttons.
the last button i was cleaning with just water running over it I saw a shield
what a shock when this design emerged after cleaning.
backmark is TREBLE GILT with the Connecticut seal in the shield.
Dan says it's most likely War of 1812 ish.
