I have heard the same about the obsidian ones being more valuable :glasses7:
Very cool, I have only found 1 in my life and I found it in the rocks on the shore at my grandpas cabin. Lots of them can be found in MN, I know a pair of old men who are brothers, there was an area near them and as kids they would find them all over the place in a field and near a lake....a huge collection! A local dam was built and the lake got bigger , forever biting all the cool stuff. But here in MN, lake shores are great places to look, lots of fishing and hunting happened at the waters edge and this is a common place to look.... And it helps that we have over 10,000 lakes here too :glasses7:
