Lack of supply, increase of demand, valuable items that are only available from them.
All cases have a set period where they drop, or at least used to.
Pretty much all the cases that were in the game through 2013 to 2015 have gone up in price to the point you have to be an actual millionaire to own them.
Especially the kato capsules and weapon case 1s and bravo cases.
Weapon case 1 is special because it has the AK case hardened in it which can go for several hundreds of thousands of dollars if you get the right thing.
Kato capsules are special because not only were they available for a very limited time they contain stickers from teams that no longer exist and from teams that were a part of a controversy so they were pulled.
Breakout cases are special because they have the butterfly knife which due to the case not dropping anymore and the supply going down blew up in price.
Bravo cases are special simply because its the bravo case and it has the fire serpent in it plus it was the first operation case.
You could go on all day about this.
