Before you go all Inspector Gadget/Sherlock Holmes on me (or look at the "Owns" tab on the suggestion), mine ain't for sale. A sexy person just gifted me this, and I noticed there was no price on it. Did some digging and some stuff (and had some free time on my hands)...SO BEHOLD, A SUGGESTION!

The last successful sale I could find (that actually had proof of what this was sold for, seems like cgreenemax bought for real world dosh, as he bought all of the previous owner's unusuals [he is a trusted real world money buyer]) was from approximately 4 months ago, as there are currently only 4 in the world.

http://www.tf2outpost.com/trade/8197344 - Sold for 3 buds and 14 Keys, which was 3.5 back then (4 months ago), as Buds were approximately 28 Keys.

One is now on Outpost ( http://www.tf2outpost.com/trade/11492412 ) but was just added, and has no offers whatsoever. The current owner is the one who unboxed it (unless bought from someone who doesn't use Outpost), so there are no past trades to use as proof.

Found the other 2 owners (besides the one selling), one unboxed his and still currently owns it, the other bought it for an unknown amount, as he is not a tf2outpost user, most likely buying it from the previous owner in a server.

Seeing as I could only find one confirmed sell, a range should not be created.

Leave feedback below, and let me know if you think this is insufficient proof. It was all I could really muster up :/
