1st - Welcome Aboard Horace! You didn't list your state (or country) in your profile. So, you might consider jumping over to Sub-Forums: Select Your Area.... for information (i.e., clubs, hunts, finds, legends, maps, etc.) directly related to your state (or country).
2nd - I moved from Today's Finds! over to Forum: What Is It? for more exposure.
I don't have much knowledge of rocks and minerals... so...
If You are asking if your finds are native American my answer would be NO.
They don't have the worked look, more like natural formed.
Sorry to disappoint, but keep looking and you're sure to find it.
