Any way to tell if these are the real thing? I mentioned to my friend that one would look cool hanging on the wall with the muzzleloader.

They certainly look old, but powder horns are easy to make.

An unmarked undocumented horn is unlikely to fetch more than $100 and that's at a high end antique shop for someone looking for a trinket rather than a usable piece.

The brass one is harder to say, the top is rather intricate and might be a patented mechanism that can be researched. Are there any marking on it at all?

Nope, no markings at all. I agree about the horns. I had one when I was young and it was just something bought down at the corner store.
