This coin was dug out of the ground at an old church in Myerstown, PA in 1984.  When I first retrieved it from the ground it had dirt clinging to it but I could tell it was in good shape.  I took it right to my car and placed it on the floor mat.  When I got home I just rinsed it in warm water.  Years later, I sent it in to PCI and was expecting it to come back as EF-45 or maybe AU-50.  An uncirculated coin right out of the ground.  Believe it or not!
