Hi ezra, outhouse, clothesline(fenceline also) stream, barn etc, are all good places to search but you said "the stone walls are still standing", so that tells you right off that if there are any goodies to be found, those stone walls have them fenced in for you. Concentrate on that area first and foremost, as it may be loaded with nails or whatever, but is likely also hopefully "Not" to have a huge amount of modern trash. If the house had wood floors, kids loved to stuff coins and whatever into them. I have found coins under old moved (torn down) houses that were literally stacked on top of onenother, so the only likely cover on the coins will be what has fallen in over the years and hopefully no one dumped trash within the stone walls.If it had a dirt floor, better yet!! That is where the folks spent a great deal of their time. It is a concentrated living area and "some" of whatever they lost is still within those walls. Smaller the coil the better for getting between the iron (masking) and better yet if you can come up on an old 100 kHz Compass (or other) that ignores small iron altogether, but picks up the goodies. Or another good one in the iron is the little Compadre, if you dont have any luck with the MXT. Great opportunity you have there and the goods are there for sure. HH, Charlie
