Anybody here an expert on arrow/spear points?

A local antique store went out of business recently after the owner died. They sold off much of his stock. One thing I picked up was a display case of about 25+ arrow and spear points, but there was no provenance for them. I’m very curious as to what I have, but the internet isn’t much help. Just because of where we live, I’m tentatively assuming that at least some of them are of Northwest tribal origins, but that’s just a guess. Local art museum is of no help.

If anybody is confident in their knowledge of these sorts of artifacts, I can send photos. Thanks.

You want to talk to dropzone. He had the answers in this thread about a spear point.
