Hi, I found this in my local town Mishawaka Indiana US and was asking any help on Identifying it any further. It seems it was Pecked then polished. It is 3.5 inches x 1.75 inches and 1 inch thick.
Yup, natural but some of the farm land near you is absolutely great hunting. My grandparents and some uncles farmed about 15 miles from you, and I found some great relics up there.
