I haven't had much luck lately, it was dry until early October, then we got a good rain. Went to an old park this morning for about two hours. I was looking for deep signals, and after about an hour got one which sounded like an Indian and was reading about 9 inches on the depth scale. CO numbers were in the mid twenties. It was iffy, but hit in more than two directions and the sound was good so I dug it. It was green coming out and I thought two-cent piece at first, but rubbed it a little and saw the "half cent". I cleaned it a little with a Q-tip and ammonia, but it didn't help much. At least it has a date. This was at a spot where I had found two large cents before, and both of them were in bad shape, one had no readable date.
