Dang you guys have some expensive knives! Knives are like guns, but you can buy them at a younger age and amass quite a collection later in life!
Well, you seem like a pretty squared away kid, and I like your thinking, but here's a "teachable moment."
I've collected lots of different things over the years from 19th century cameras, to early 20th century arts & crafts pottery, to wood block prints and I learned that quality costs and quality is worth having. That goes for collectible items as well as for stuff that you plan to use daily.
Knives and guns fall into this philosophy as well. I seem to have a small collection of knives, but most would be classified as users and I've accumulated them over many years. I've probably carried 95% of them in my pocket at some point. If I could afford to have "collectible" knives I expect that I could spend several thousand dollars in the next hour.
With guns, I'm not a collector. I'm a shooter. And quality is worth it there, too. I am a clay shooter and have two shotguns that cost me more than every other gun I've ever owned...combined. But, they're great guns, fit me well, and I expect that someone will inherit them from me.
So the bottom line here is...don't just buy stuff because you want a collection. I'd rather have one great knife, or a few great guns, that I enjoy using and will hold their value, more than a safe full of ho-hum stuff. Same thing for collectible/historic stuff. Buy the best you can - quality and condition matter. A friend told me once, "When you are considering adding something to your collection make one of your criteria - who will you sell it to?" Took me a while to figure out that was really good advice. I've never had any trouble selling anything and I've never done worse than breaking even.
So choose wisely. Do your research, look at what you can comfortably afford and then save more $$ until you can get a better one or something in better condition.

The "value" has nothing to do with dollars.
