Indian Arrowheads

Any collectors of arrowheads on the board?
I have these 9 arrowheads, and what seems to be a hide scraper (maybe, maybe not)
They have been collected from AZ to the Dakota's mostly, and I was thinking to let them go to someone who will appreciate having them.

They are in AZ, and the long black one is 3 inches (for a size reference)

Any idea what I should ask for them that would be fair and a good deal for a member.

Thanks.
