Yeah, my first thought was Celtic too, but I haven't been able to find any matches online... These coins must have a very interesting story (especially the golds) because there's no reason they should be there. If they are real, they WAY pre-date any British activity in the US. The KGIII's are not out of place, but the quantity and quality of them is incredible. How many square feet were there coins found in? Were the gold pieces all together?
