NICE FIND! You should put a coin or something in with it and post a new pic so we can tell the size.
I've got a rust colored mercury dime I detected in the 80's on the shore of Hyennis Port Marina. (spelling, I know) It's about the same color as your point! Funniest color silver coin I have dug.
Wow, I could be wrong and would like to hear other opnions......but the middle point above looks like a Clovis. If so, its approx 12,000+ years old and worth a few bucks.
Nice, very nice. You should post them in this thread: North American Indian Artifacts
And, like what was mentioned already put a coin in the picture for a size reference.
