I dont mean any disrespect to you or your friend but there are many obvious reproductions in the group including the McCormick Folsoms and Sandia points. I hear this phrase quite often that "so and so has been collecting for xxx amount of years and he can tell the difference." Honestly, it doesnt matter if somene has collected for 200 years if they've never been taught the difference between authentic and reproduction they are doomed to get duped. I'm sure your friend is an honest guy but hunting collecting for 40+ years is not a great qualifying statement for being able to tell authentic from modern. The Folsom points are most certainly McCormick and the myth of Sandia points has been all but debunked. I dont believe there is such a thin as an authentic Sandia point.
Here's a little background story about the points found at the Sandia site which should lead you to believe they are all but bogus and likely planted. Read a little more about the myth of the site and the controversy it held. It's a pretty interesting story.

Again, no disrespect to you and your friend. There's a lot of knowledge on these boards and for people experienced in seeing the reproductions those are fairly easy to tell in my opinion.
