I have a friend who inherited 900 pieces of primed 223 brass that has been trimmed, camferred and appears to have been annealed at one time. The head stamp says 1v1 92 and some other mark I can't make-out that kinda looks like @, but I don't know for sure.

I am NOT looking to sell it, will NOT sell it to anyone under ANY circumstances, but am considering buying some or all of it for myself if someone can guide/advise me on it. I don't even know what it is.

Can anyone identify it and guide me a bit on what would be a fair price if I were to make him an offer?

Thank you.
