This is a great hat (not such a great effect though). I feel this price should be bumped up, and please comment with counter proof or suggestions. Remember that this price is on the old side, and I have provided every trade on outpost, with history for some of the newer ones. Thank you.

No offers after a month.

Bought it at 20 keys. http://www.tf2outpost.com/trade/10044839

This guy has two trades, so I won't list the other one (it doesn't have any offers either).

New, but he bought it for about 20 keys (a BMOC + a Bills) http://www.tf2outpost.com/trade/11032274

http://www.tf2outpost.com/trade/11204194:

New, so no offers. Tried to follow the history on this one, but it seems this guy moved it between accounts, so its hard to find.

http://www.tf2outpost.com/trade/11166334:

New, so no offers. Looking for $30 (about 16 keys)

Could not find in history, as its previous owner's most recent trade with it had no real offers. http://www.tf2outpost.com/trade/9830729

http://www.tf2outpost.com/trade/10904613:

about a week old, with no real offers.

Not bought recently, and the previous owner has over 600 trades, so I couldn't find it.

http://www.tf2outpost.com/trade/11207862:

Only accepting 1 bud.

Unknown how much he paid for it, as he commented in this trade which marks it as sold (so he bought it from this guy). http://www.tf2outpost.com/trade/10673298 However, he says he is looking for 22 keys here (although this is not very good proof) http://www.tf2outpost.com/trade/9934102

http://www.tf2outpost.com/trade/11025035:

b/o: about a bud

no real offers, history unknown (previous owner has only one trade, which was closed for inactivity http://www.tf2outpost.com/trade/10157195

http://www.tf2outpost.com/trade/10692365:

c/o's: Black Bill's (8-9 keys) + 8 keys + 6.22 ref (about a key and a half, as keys weren't so expensive back then) + sweets (rejected)

20 keys

23 keys

Craft # hat, which is almost impossible to value

Offers: Strange Machina (18 keys, which was about 19 when the offer was made)

No real history

http://www.tf2outpost.com/trade/11107742:

looking for an upgrade, history: none really, however 2 owners ago was looking for 17 keys

This took a really long time with all the proof and history, so please leave comments with your thoughts, counter-proof and suggestions. Thanks.
