You've got some good ones! You got some Lecroy- (check out these examples and see if you don't agree):
Lecroy - LITHICS-Net The one on the top center of first pic is really nice!
In pic 3 you have a drill, I think at top- black. And either a Madison (or a knife blade) left, under the coin. And under the black drill, a Levanna triangle (or some sort of triangle and another below that- look small enough to be a true arrowhead (as in bow and arrow), perhaps.
and a bunch more. Some (many, I bet) used as knives. In general, my thoughts are the first 3-4 pics are your best. Some hard to tell because of the angle of the picture. Of those pics, choose 5 or6
you think are the most beautiful - well made, symmetrical, nice lithic... And if you use natural light, they might show better. Thanks for those! The Lecroy, McCorckle, (Kirk)- types- the ones that have 'ears'- called
bifurcated, They're my favorites in the lot- those and the triangle frame. (but that's just me
