The first item is lightweight and reads "One run, 6 Rush". The second item is flattened out and looks silver plated. The third item is ???. Fourth item is a button but with a strange design. Fifth item is lead with a design but no idea what for. All were found a various cellars this year.
Second one looks like a tip to a leather belt or strap. The button is probably a civilian fashion one. Is it one piece? The lead looks like it might be a fired bullet from a modern muzzle loader. How big is it?
The two ring and three ring style do have a little cup to the bottom, but no design beyond the rings (altho I know the rings are not for an asthetic design). The fact it has a ring/lip just below the cross pattern makes me thing it was from a shell. Maybe a real early one when they first started using casings. Now they all have a flat bottom, but yours has a deep cup. More modern than civil war.
