1964 Error Over 4

Ok I'm still new at collecting coins... but I'm familiar with metal and saws... 1) yes if cut at a angle it would leave a grove up but it would peel off in places not leaving that grove the whole way, 2) to leave a li like that would require a serious angle.... one thst I just dont see if you note on the 4 were it is "cut" you would see a slope at the bottom. .. one I just dont see. 3)if it was a cut then it would raise up perfict on the s n the 4 the way it does to me it looks like something got stuck on the die 5) if it was a cut again a angle would have needed to be used n that shadow wouldn't cover that angle with how small thst shadow is you would still see a cut.... thats just mho this dont spell cut to me
