I will give you a little history on the area I was searching in today. Late 1800's early 1900's this area used to be a mining zone. Several 40 plus years ago they turned it into a park. Now they have a newer area that is the park today. I searched in the old park and found this. I was about 8 inches down. I was reading as a coil at the high end like 50 cent piece or dollar. I don't know what it is made of maybe you have an idea???? None the less I thought you might have an idea on what it is?????
Thanks,
