This is my very first suggestion. Please go easy on me. :<

Only TF2 Outpost seller with a price:

http://www.tf2outpost.com/trade/15407429 <- 1.55 ref + gift wrap

TF2 Outpost search link for future reference:

TF2 Outpost search link for buying offers (clean ones) for future reference:

TF2 Outpost buyers (EDIT: clean ones):

http://www.tf2outpost.com/trade/15403326 <- for a key

http://www.tf2outpost.com/trade/15385203 <- 1.11 ref

Couldn't find any Bazaar.tf offers.

Current Mann Co. Store price: $2.49 / £1.49 / 1.79€

My suggestion for now is 1.33 to 1.66 ref + gift wrap. I know this stuff is hardly "proof", but I think for a short-time temporary price until more of these are offered and sold, this is okay.

I would love some constructive feedback, as I am entirely new to suggesting prices myself. Thank you.

PS: Please note I am currently trying to sell one myself and I'm not doing this suggestion to make a big profit or anything. I'm just trying to make my first suggestion and I want it to be alright. If you think my suggestion is bad, feel free to downvote it or make your own suggestion. I hope to learn something from this.
