Are there any item which gives Cold Iron property to weapons?

[Shin Okada]

Gauntlets of Weaponry Arcane (MIT P.104) let held weapons overcome DR as if it were a magic silver weapon.
Ring of Adamantine Touch (MIT P.121) makes melee attacks overcome DR as if it were made of adamantine.

Are there similar item to make weapons or attacks considered to be made of Cold Iron for overcoming DR?

One right from the core.

Also the Weapon Capsule Container with Quick Silver capsules out of Complete Adventurer.

That's a bit harder to come by, as wotc was (maybe not so in 4E) a bunch of demon-loving @$$-holes.

They even tried to argue in the FAQ that you have to pay 2000 gp EVERY time you enhance cold iron. I swear, Skip Williams and co. were in the thrall of orcus.

That's because its what the DMG states and how it was ruled within RPGA. So make sure you save up for that +5 cold iron holy sword

No, it should not cost any more to enhance a sword from masterwork to +1 to +2 to +3...to +5 than it does to go straight from masterwork to +5. That's beyond unbalanced, it's just ing stupid.

And the RAW says you have to pay 2000 gp to enhance it. Not every time you want to enhance it. So it's just as fair to rule it as an "initial fee" for it to be enhanced, paid the first time only.

The metalline property. +2 enhancment property. Lets you change the composition of the weapon as a standard action(I think)to any other material...I think it only applies for purposes of damage reduction....but I might be wrong about that part.

Unfortunately, it actually changes the composition of the weapon. Thus, that is no different from a weapon actually made of cold iron and much expensive (especially considering that I can have virtual Adamantine/Cold Iron/Silver weapon by using above-mentioned ring and gauntlets).

If some non-weapon item can give Cold Iron property to a wielding weapon, I can get similar result with a weapon not made of Cold Iron.

This seems like a good idea for a weapon crystal. Why not just write one up based on the analogous crystal for ghost touch?
