I forgot to post this so I will now, a few months ago I was at my closest cellar hole site. I was detecting to the right side of the foundation when I hit a high 80s low 90s signal on my AT Pro. I dug down about 7 or 8 inches and pulled out three coins; a 1812 Russian 2 Kopek Copper, a 1795 Liberty Cap large cent and a 1832 matron head large cent in great shape.
This without a doubt is my best find to date, I don't think I'll be able to top this find for a while.
