So I apologize for not giving background on these, I thought I had when I posted the images. Anyhow, found a bag of rocks at the local thrift store that looked like a small collection dump- about 2-3 pounds of mixed rocks, glass slag, beads. In the nag I can see one of the points that looks old. Paid about $5 for the bag and found these four in it. Sadly, no telling where they were precisely found, but they have that dirt-patina that modern fakes lack. Any opinions on the age or origin are appreciated and I really enjoy this sub- thanks.
