Three Similar Knives in Question

[Paladin]

Hello Guys and Gal, I need a little help to settle a friendly little dispute between myself and a very good friend and mentor.
I am attaching a series of photos on three fixed blade knives and all are etched on both sides of the blades. All handles are horn and the black one has a small insect divot. It’ll likely take two posts to get them all posted.
My friend feels like these knives are ancient or almost so and that they might be historically significant because of age.
I have maintained that they are very much like most of the Hispanic (made in Mexico) knives that I have seen. I have not seen others that are etched on both sides of the blade. The etches are mostly floral with a few birds thrown in for good measure. I have no clue who might have made these or if the artwork might be significant.
If any of you are familiar with any aspect of these, who, what, why or when, please jump in. I know value might be a lot to ask, but I would also be interested in whatever thoughts you might have on that subject.
As always, any help will be appreciated.

They look Mediterranean to me. Like Corsica, Malta, Iberian peninsula, France, or italy. I know the Mexican ones but they got their ideas from Europe. I don't think they are ancient but maybe mid-late 1800s. They still do the panel etching in the countries above and make the same knives so it is hard to tell age. They are not uncommon and I think you win!

The etch on the blade and the shape of the guard as well as the handle material identifies it as coming from oxaca mexico.
