Delareece Valued Member Canada 101 Posts	Posted 12/02/2012 5:49 pm Hey there, It's been a while since I've posted anything, so I decided to ask this question. As I was roll hunting pennies yesterday, I came across this 1998 penny with damage. I'm fairly positive this is PMD. My question is, what would cause this damage to a penny? I've never seen or heard of a piece of a penny literally "breaking" off. It appears to have snapped off somehow. Any ideas? Additional Information: If you can't clearly see it on the images, the edge where the piece appears to have "snapped" off is very jagged. It isn't a clean cut. The rest of the coin is not bent or mis-shapen in any way. Also, the white substance coming from the broken area is not on the coin... it appears to be "in" the coin. The copper plating seems to "fold over" and "flake" near the edges of the white on the Reverse. Obverse: Reverse: Angle: Edge: Edited by Delareece 12/02/2012 5:50 pm Report this Post to the Staff

It is a corrosive reaction from environmental damage.
