I had a neighbor put in a brick walk and they dumped a bunch of sand and half of it never got used. The local kids knew what it was good for and played there until it was all spread out. I was walking home from school (1969 or 1970) and spotted something shinny in the dirt and I gave it a kick to loosen it up and one of these poped out of the sand. I also got a D type but I think it was from some where else.
