Why would 1938 buffalo nickel in very good condition have a brass tint?

This tint -- known as toning -- is caused by exposure to contaminants, like dirt, the oil in peoples' fingers, stuff in the air, or from some kind of liquid The contaminant will chemically react with the metal on the coin's surface and cause it to change color.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
