My Grandfather traded some of his points for these museum quality Awls back in the late 1930’s with a fellow collector. They are from the Wisconsin area and are from the archaic period, likely 3,000 to 8,000BC years old. I have compared them with other awls on-line and lesser, smaller awls sell for about $125.00 each. These appear to be even better quality than the ones featured at the Milwaukee Public Museum (www.mpm.edu) in Wisconsin. They were largely used as perforators and stitching animal hides.
I added a photo of an example of how some others look.
It was evidently a big discovery that American Indians were using copper that long ago. I look at them and wonder about the hands that used them for crafting everything from clothing to shelter cover and more.
These are very rare! Priced to sell!
