Friday hunt - 3 wheats and silver ring

I went to the current school I am hunting and had made up for my 2 days of finding just about nothing. I manage to find 3 wheat pennies and a silver ring along with a buck 55 in clad  I have found 4 wheat pennies total here in 2 totally different areas. So I'm hoping that silver coins are in the mix somewhere.
