At first glance, they look like the kind of thing Frost Cutlery cranks out by the hundreds of thousands. The knuckle guard on that first one looks to be made of aluminum, and the fact that the handle slabs stand out above the metal at the pommel there are clues that these might be wallhangers.
It would help if you could pass along any writing on these knives, and more photos, especially of seams and joints, would help determine what sort of quality level we're talking about.
I don't know how much lurking you've done, so I'll post the usual heads-up:
Registered users (like you and me) are not allowed to ask about the value of any knife or tool. Likewise, we are not allowed to sell or buy knives in the regular forums. There may be exceptions to this that I am not aware of. If you are interested in commerce, you can contact other members via their member profiles.
