It seems you are always learning something. I have been searching an old house now the few outings and have been frustrated. I am finding fist fulls of coins but nothing old. I have also discovered coins everywhere they really should not be. I discovered that almost all the Zincs have nicks in them. The guy that owns this house rents it out and mows lawns on the side using Commercial grade movers. I really think now that the mowers are picking up these fresh drops and scattering them everywhere. I am betting he mows really close which causes the mower to suck up the coins easily.
