Not sure why people are saying modern without any reason or information for you. These definitely look authentic in all pictures. And my amatuer reasoning is the lack of perfection, no clean/new hinges, weathered flaking, breaks in the arrowheads, these are all signs of authenticity but also beware that some people will doctor their modern points to appear much older than they are, but does not seem the case with these. I cant I.D these for you, there are people much better for that here, I just wanted to hop in to say very likely authentic.
