Coin Cleaning Solutions: BU Plus Coin Cleaning Solution vs. 1943S War Nickel

High Plains' Mike E. (a.k.a. The Metal Detecting Beast) recently had an encounter with a target he couldn't at first identify. With a little work using BU Plus coin cleaner/solvent, he was able to unmask his find and reveal a beauty of the coin. Here is Mike's Story:
"The coin was found in between two roots at the base of a large tree. It appeared to be encased in a dark hard shell, possibly dried tar.

History
The United States introduced the war nickel on October 8th, 1942. These war nickels contained no actual nickel. Silver and manganese were used to replace nickel. The purpose of the war nickel was to conserve nickel, a critical wartime commodity. The government needed nickel in order to fight in WWII.
