After a bit of trial and error, I finially found a way to thin and bend coins that will be useful after a bit of practice. My only roadblock is the burnt black stuff left on the coin after being thinned. I tried a crude method of buffing (I'm a total amateur at buffing and don't have a decent buffing system yet) and it got some of it off, but began to wear down the details of the coin. Any ideas on how to deal with this? The coin pictured is a copper 1981 penny from my pocket, I didn't pay attention to how it was oriented, I just bent it.
