Now that's Good Luck .
Hope there is more but in my experience / unless the house is pre 1964 or Rich Drunks lived there , much aluminum is waiting to be found , no better place to dig it all esp, in the Summer.
Truly wish you more Great Luck.
My optimism comes from the first yard I got the courage to ask permission for in 2011 , I scored 2 Halves '1 benji' 1 , Walker , 2 silver Washington's , a Mercury Dime , & a Smooth Barber Dime. + a nice Civil War Bullet. & Other Old Brass what is it's.
I have never come Close to a score like that one since except for a home across from a Elm, School that been in use since the early 50's ..7 Silvers from there.
Again Good Luck.
