I found this penny in my yard as my first TRUE metal detecting coin find. It is a Memorial penny, but with a strange oxidation pattern. I know the copper in pennies turns them green when they oxidize, but how bout white? Is it jut a more uncommon form of oxidation or is it made of a different material?
