Why exactly are they so valuable?
I know it's about something where you spent 15$ in a single purchase, whihc is now replaced with the Mann Co. Package.
 
I think its because this weapon was not allowed to be sold from the store, but there was one way of getting it from there anyway.

Due to this weapon's strong resemblance to the ADAM Harvester from the Bioshock series , Valve requested and subsequently received permission from 2K Games to include it in Team Fortress 2.

Due to copyright reasons, this item is not sold in the Mann Co. Store.
 
They are only as valuable as people make them, the reason why people price them so much is cause they are rare now and you cant get them anymore, it used to be from the $20 in store and randomly get it, but now since they put in the mann co. package you can't get uncraft versions anymore. I personally think the uncraft vita-saw, sun on a stick and sharpened volcano fragments are stupid, it's just like any normal dirty weapon to me
