Dug Revolutionary War American Artillery Officer's Sheet Copper Coat Button

Dug Revolutionary War sheet copper American artillery officer's coat button. It has a pleasing green and brownish patina with some dirt still present. It originally had a wooden back. The detail is super crisp and the button is solid with just some waviness and a tiny pinhole in the center of the wheel. It is a very nice example of a dug Continental artillery officer coat button. It measures 24 mm in diameter. $895
