What Junk in Fallout 4 isn't really junk? [duplicate]

Fallout 4 adds the kleptomaniac-friendly ability to deconstruct practically anything into useful components. As such, I have built an impressive store of building materials, and enforce a "pick up everything, leave nothing" strategy. This works quite well.

However, a few guys on Live have been recommending I hold on to any copies of the Daily Bugle I find, as there is supposedly an NPC that will pay caps for them. I assume this is the case for both regular and rolled up copies.

I know that in previous Fallout games, there were a few "junk items" that would serve a purpose, often in regards to an NPC that would buy them off you for a fair amount of caps.

Are there any junk items in Fallout 4 that serve any type of purpose other then component scrapping? Are there any particular items I should be holding on to, instead?

I am specifically asking about items that can otherwise be lost through the automatic dis-assembly of junk. Items that fall under the "misc" category, like overdue books and subway tokens, are of no use in this context as there is no great risk of accidentally destroying them.

Solution 1:

There are many scrappable junk items that can be used whole for other purposes, for instance for specific quests or as a crafting ingredient:

Used for Quests (repeatable quests italicized)

• A Biometric Scanner and a Military-Grade Circuit Board are required for the main quest The Molecular Level.
• 4 High-Powered Magnets are needed for the Brotherhood of Steel quest Liberty Reprimed, but they are provided in the Boston Airport workshop.
• Yellow and Blue paint cans - Abbot (Diamond City)

• Skull - Spiked Pole

Solution 2:

The big one that I try to avoid scrapping is Pre War Money.

Cloth is easy to come by, and Pre-War Money has a high resale value and zero weight, which makes it an ideal way to pull caps out of an ATM machine trade with merchants for a few extra caps whenever you come across one.

Solution 3:

Actually, I've found a handful of items worth holding onto, if only for their caps/weight value. If you currently don't need the resources they provide for crafting.

• pre war money (kinda obvious since its higher value than caps and has no weight)
• gold anything (watch/locket/flip lighter, if you need gold for crafting, scrap the flip lighters and lockets, since the pocket watch doesn't weigh much and has a really high resale value)
• synth components (sell them instead of scrapping them. They sell for 50-100 caps each, while scrapping gets you 2 plastic which is super easy to get from a million other things)
• packets/cartons/boxes of cigarettes & cigars (almost no weight and a decent sale value. they only provide useless cloth if scrapped)

Just a few ideas. basically just compare the weight, scrap components, and sell value to know what is worth picking up/scrapping/selling. I usually dump all of my 'to keep/sell' items on dogmeat as I go (since he's the the only companion that doesn't collect random crap on his own) so when I get back to my settlement I can just dump everything without thinking about it.

Some npcs will trade random junk for caps (like the guy who wants tools) but usually the price isn't worth the time it takes to constantly travel back and forth to drop it off for the petty amount of caps they offer.
