So goddamn many of these in crate sets/unusual offers trades/cashing out/etc.

I'll post everything that's not one of these.

BTW the amount of buyers (~5 pages) is much greater than sellers (1 page)~

http://www.tf2outpost.com/trade/14224231 - No offers.

http://www.tf2outpost.com/trade/7930650 - Very inactive lately, offered bud + 5 keys and 28 keys pure

http://www.tf2outpost.com/trade/6918290 - Offered bud + 4 keys

http://www.tf2outpost.com/trade/9168526 - Also inactive, offered 28 keys

http://www.tf2outpost.com/trade/10859103 - No offers on 30 (puddington seems to have sold some tho, what they went for is unknown)

http://www.tf2outpost.com/trade/2555361 - Offered bud + 5 keys

http://www.tf2outpost.com/trade/14227778 - Sold for bud + 2 keys

http://www.tf2outpost.com/trade/14160340 - Buying for 28 keys

Pretty much all of the other buyers on op are quickbuyers.

These seem to have gone up in demand along the other salvageds, possibly because of rarity.

Also, market may not be the most valid proof, but

These have risen a little bit, to ~$70, taking keys' market value, it's somewhere around 32 keys. Since crates aren't really seen going for that much elsewhere, I won't include it.
