My house is built in 1842, but I have never found a silver coin. I live in upstate NY.
Looking at some old maps of your area might show buildings that are no longer there: houses, schools, churches, businesses, perhaps a former fairgrounds, maybe even a town that is no longer there.
I'm curious about the yard of your house. Is it a fraction of an acre in a city, or are you out in the country and have some acreage? Have you found any old coins or relics near your house?
Do you know if all or part of the yard had had fill dirt added in the last 50 years? If your yard has the type of trees that have root systems stretching out a few feet and you can see them, the area probably doesn't have fill dirt. Erosion on hills can keep old coins shallow.
I live in a suburb that had no parks before 1963. I found 11 silvers in a 1963 park, and 3 silvers in a 3 acre 1964 park. I detected a school that opened in I think 1972. My finds included 1961 GW quarter, antique ring likely silver, and a 1907-D Barber Dime 2.5" deep. Used to be a farm where the school is.
Detected a park made about 1990. Got a silver Roosevelt fairly near the new sidewalk. Near a green electrical box, got a 1892 Barber quarter 2.5" deep. There used to be 2 farmhouses there. The area was bulldozed, but they didn't want to go too near the sidewalk or electrical box.
Wikipedia is pretty good for listing true ghost towns and usually has articles on very small towns that are still there and never were big. Another site that has locations of old ghost or near ghost towns is hometownlocator.com/ It has much other info as well. Historicmapworks.com has many old maps of places in NE US; also on maphistory.info decent collection of maps under US states and areas; amount and type of info varies by state, Best wishes.
