I was working a section of the backyard where we pull in, an old gravel drive. Got a solid it and dug this. The date is 1888 when examined under magnification. No clue what kind of coin it is. The other side is worn smooth from years of being under the gravel. Help please The Compadre nailed this coin with a solid signal, it was about 6 inches down in the pulverised old gravel.
