Spending the day off doing what I assume most of us do, going through coins, lol. I came across this one and thought improper alloy mix but after looking closer I'm not so sure. The lines seem a little too consistent for an alloy mixing issue and it doesn't really carry over to the reverse. The only thing else I could come up with was the roller that makes sure the planchets are the correct thickness was damaged or worn. What do y'all think?
