It has taken the assistance of experts to learn what I found a month ago in a Fair Grounds/former 19th century homesite. I was shocked that it was more than 100 years old because of its good condition. I think it is either bronze or some mixture of brass and copper, as it is as found, except for washing and peroxide bath. I found it with the GTI 2500 in an area littered with clad coins and modern trash. This is quite a surprise.
