Hey @bdunnse, I was trying to send you a PM but you have decided to not like me, your fellow beer lovin' Who Dat. So sad OP, your coins have met with a grinder, parking lot, flame thrower and a shark. Sorry, no premium on these.
I would say the penny has spent a little time buried in the garden. That type of corrosion is common where fertilizer has been used. I have a few of those myself. The nickel is road rash in my opinion. . Cheers!
@Kirkuleez I don't know why pm doesn't work, but will look into it. Meanwhile I started a conversation I think. edit: I think I fixed it.
