Like, is there going to be someone who wants to buy my Pre-war money? Am I going to need intact Biometric Scanners, Enhanced Targeting Cards and so on?

If it is in Junk section of inventory, is it safe to scrap it?

Save 1 Biometric Scanner and 1 Military Grade Circut Board, I won't spoil why but you need them and there a pain in the ass to find again if you waste them like I did.

Other then that I don't know what else you need to save, I'm still only 20ish% into this game.

I would say that you want to sell very little of it. All of it can be used in construction at any of your outposts. Since you obviously don't want to carry that around everywhere you can drop it off at a "Workshop" at an outpost. That's the red workbench where you start building stuff. I suggest putting everything in the one at Sanctuary and moving it to other locations as needed. Better to use it then sell it. Caps don't seem quite as useful in this game from what I've seen so far.

Thanks for the tip

1 teddy bear. Give it to your dog instead.

Awww, will do

If he does nothing, ask him to do tricks

Prewar money is expensive and its a much better option to sell it than scrap it

Thanks for the info.

So far I have found that these scrap-able items can also be used whole in recipes:

Abraxo Cleaner

Antifreeze Bottles

Baseballs

Bloatfly Gland

Blood Sac

The rocket, alien, teddy bears, lunchboxes are nice to display in your house

But yes, pretty much scrap everything...
