Don't try to bump the value of your item without proof.

http://www.tf2outpost.com/trade/4994360: BO of 1.7, CO of 1.4

http://www.tf2outpost.com/trade/4508566: No BO, CO of 1.4

http://www.tf2outpost.com/trade/4998934: Your trade, no offers worth mentioning

http://www.tf2outpost.com/trade/4875425: No BO, CO of 1.5

All of these are in the old price range, CO's at the lower end and the BO at the higher end.

Along with ^that post...

"believe these are rising, due to christmas" No, Its a crappy hat, They might be inflated due to Christmas though.

"themed (renewable rescources, nuculear, engineers etc)"

I call bullshit, Dont make up themes.

I believe they are not rising.

The whole mindset that these along with the other Christmas themed things will rise is stupid. You are telling me that you will pay more for something just cause it is close to Christmas?

What's the theme? Marginal at best.

I recently sold mine for 48 keys, it took long and going through a few trade servers before some engi fan decided to buy it.

Oh yeah nuculear
