I'll be interested what these look like all cleaned up, especially the legionary denarius (hint, hint).
My son the detectorist would be ill seeing all this. Nothing ancient in metal here in the good ole USA.
Here's a similar one found in the 1970s by my dad in Lincoln County KY. I've got a whole box of them back at my parents' house somewhere, collected from all over the area.
If you use a metal detector on high ground near flowing water in the spring after the rains come you will find coins and arrow heads sitting on little pillars of soil. Deeper coins will also be read by your detector. If you find a lot of surface finds you might want to dig and sift the soil.
