I hunt in the Pittsburgh, Pa area. One of the places I've tried is a place on the North Side of Pittsburgh which consists of two parks, East Park and West Park. Last year I read a book on Allegheny City, which is what this North Side area was known as 100+ years ago. It closely borders the Allegheny and Ohio Rivers directly opposite downtown Pittsburgh. East Park was, in fact, a much used area where people lived and congregated during the early 1800's. During the 1700's whitey ventured over there on occasion but it was mostly peopled by hostile and violent kill for sport Indians. In this entire area of two parks I have found nothing older than Barber dimes. And I've got them at 10+ inches. Where are all of the older coins, the seateds and the capped busts, etc. I don't know if I've seen a post on this forum with any bust silver. Do these coins simply go to far into the ground to find? If anyone has hunted very old areas and found stuff could you make a few suggestions. The soil is highly mineralized and there is a lot of trash in these parks.
