Really cool looking at it. Know what causes the coin to do this? Is there value in penny's like this? Report this Post to the Staff

RoyCoinBoy Pillar of the Community United States 1609 Posts	Posted 07/25/2017 09:24 am The toning itself carries very little to no premium, and those bumps are caused by zinc rot. Toning happens when one substance reacts with the metal on the surface of the coin, therefor changing its color. Report this Post to the Staff
