Hi, I'm pretty ignorant about this stuff as I do not hunt for treasure per se, but stuff falls into my hands sometimes. I live in northern Illinois near Chicago. Couple months ago I found something piled on top of some rough quartz and smooth limestone ballast around a sewer outlet that put water into a weir near the Fox River. I had to do a lot of searching to identify what it is meant to be. But is it real? It's in "war hammer" shape, white quartz, quite clean, a bit chipped. Research also told me it's likely fake. I have to say I felt it was fake when I found it - it is so clean. But it's a lovely shape. Very comfy fit to the hand, very complex in design.
Now I will go see if I can figure out how to post a picture of it.
