We had a farmhouse on our place it was built about 1911 I think.
Found some pennies from the 19-teens, 3 or 4 V nickels and a Tin Type 3x5 of some young man, that was probably older than that house.
I have lost track of that tin type, several moves over the years.
We have a log cabin also that is still standing mostly, from the 1870-1880s. Never found anything in it.
