Never really do this kind of hunting.But i read john tips and though i would give the small coil another try started hunting close to school from 1962 then i started to pick up what i though was re bar.There is also a lot of junk in this area i think the dumpster was here when they built it.When i pulled the first penny i knew the rest were coins in a 2 foot long and 5 inches wide area depth to 4 or 5 inches.It must have been were they tossed pennies against the wall,the oldest is from 1959 to 70s.
