1934 Brown Colored Buffalo Coin 0

[LoveToCoinHunt2]

Can someone explain why this Buffalo coin is brown colored? Out of all of the Buffalo coins I’ve come across, I have never seen one like this.

   This well circulated 1934 "Buffalo" nickel has corrosion or "environmental damage", especially on the reverse.  U.S. nickels are composed of an alloy of 75% copper, 25% nickel.  Copper is a very chemically active metal and is readily subject to discoloration and corrosion. Such coins are considered impaired and have less value than unimpaired examples.
