When I was a kid I acted like King Farouk also.You're not going to learn until you get it out of your system.Don't just do it to this half but several and then put in staple 2x2's.Bowl of water and baking powder.Moisten coin and rub powder until cleaned.Several years down the road some will retone.Bottom line-it will only be worth siver content.But aint it so beutimus!
