Strange find form a small town park in Illinois!! After digging the usual clad and wheat's I received a high conductive hit.. I retrieved the target which I thought was scrap brass or copper.. On the way to my trash pocket I noticed a design and thought "I'll clean it just to see what it is".. Went on hunting and found a couple of Indians which make 16 this year.. Well I was shocked to say the least!! Possibly roman and dates from 100BC to 200AD.. I figure dropped by a kid on the way to show and tell.. Just the same as the ancient Japanese and Chinese coins I've found here..
