Went to a local camp ground here in Louisiana.Sorry about the bad picture,don't know what happened,a couple of Quartors,not old 1964 and 1967,couple of dimes mid 60's pennies mid 70'S.Also looks like some old 3 liter screw caps don't think they make 3 litter soft drinks anymore.I was tripped out these caps read high tone silver is this the right reading for screw caps.I checked in advance and salt same reading.Again sorry about the pics,They are cell phone pics but should have been better quality.
