Yesterday I searched a church yard for about an hour. I found one stinkin Lincoln,an assortment of nails,bottle caps,pull tabs,a .50 cal. BMG bullet AP and what I thought was a piece of aluminum scrap. I did get a very nice 87/88 reading on it. I took it home gave it a bath and it turns out to be a very ornately reliefed bottom to a cigarette lighter case. It is stamped Sterling S on both sides. It weighed in at 19.9 grams. In hind sight I should have looked for the top. From now on I'm going to golf tee every area where I find something valuable and go back to that spot again before I leave the grounds.
