Hi Seeker,
The metal detecting finds are very nice, but you may be missing the larger part of the treasure at this site. The coins indicate a very early settlement. The cellar holes may very well contain more treasure than you think. A lot of time when a cellar hole was not used anymore it would be used as a trash pit. Many cellar hole have produced very nice bottles. If just one of those holes was used as a trash pit , you may find some very early and very nice bottles. Try your metal detector right over the holes and see if you get a reading for scrap metal. If you do , there is a good chance that bottles will be mixed in. There is some very cool history to the old bottles , not to mention some good $$ for the right ones.
Good luck on your future hunts , and I hope you find some bottles too!!
