What do you pick up while MF'ing?

I'm curious to hear what kind of items people pick up while MF'ing or playing in general, and why. Runes, uniques etc are a no-brainer, I'm more interested in items with "hidden value" that not everybody necessarily understands. Here's my 2 cents:

I pick up and save

• Most elite ethereal armors (for bugging)

• Ethereal
  Thresher and CAs (socket in cube, hope for 4s, good base for Infinity.)

• Phase Blade (socket in cube and hope for 5s or 6s, a good base for many purposes)

• 4s and 5s
  Flail (bases for Heart of the Oak and Call To Arms, often worth a
  Pul. Easy money)

• Normal
  Coronet (for
  Charsi-imbuing. Never imbue anything else, if you get nice rolls it's like winning the lottery)

• Flawless gems, to turn into Pgems, to be sold later in larger quantities for runes. Same with jewels, never toss any away. (
  Perfect Amethyst and some jewels I keep for myself to craft caster amus)

• Wand (s), no matter the quality (even with just a few +skills you'll often get the max gold value at vendors. Since they're small, they won't fill your inventory as fast as armors, for example. Having tons of gold is nice, so I can gamble for +3 amus or coronets for example)

I would pick up a lot of magic items with potential. Such as magic jewels to get a

Ruby Jewel of Fervor (15/40) for example, those are worth quite a lot.

Or magic rings/amulets with high rolls of MF.

And ofc JMOD's and JSTOD's (Jeweller's

Monarch of Deflecting and Jeweller's

Sacred Targe of Deflecting), which are shields to use with the cube recipe to get 4 os to use with fx the beforementioned jewels. Both are magic shields.

I always pick up crafting materials in addition to the obvious items. Magic amulets and rings, the various runes for blood amulets and rings and

Hit Power Gloves. People tend to forget you can craft some amazing gear.

I like to hoard Bases (especially Ethereal ones), gems, runes and jewels (to craft), charms and a bunch of Class-specific magic/rare items.
