Might as well be my first suggestion, I haven't done one in over a year. Well either way I believe this is ready to go up, up and up! I had the glory of owning one of these, but I got scammed so whatever.. >_>

Sale #1 - http://www.tf2outpost.com/trade/20367103 - I bought it myself for 75 keys. Buds at the time were considered 16 keys. 75 / 16 = 4.7. Proof is literally in the trade I bought it, but before and after of my Backpack..

http://backpack.tf/profiles/76561198084375587?time=1403506800 - Before the trade happened. (Look at the stuff I used to have. q_q)

http://backpack.tf/profiles/76561198084375587?time=1403593200 - After the trade happened. 75 keys on page 4 and 5 are gone.

Sale #2 - http://www.tf2outpost.com/trade/21091272 - Sold for a Cauldron Bubbles Armored Authority + 2 buds. (3.25 * 0.9 = 2.9 + 2 = 4.9)

http://backpack.tf/profiles/76561198078227700?time=1404802800 - Buyers backpack before the trade happened.

Sale #3 - http://www.tf2outpost.com/trade/20092941 - Sold for a Flies Flipped Trilby (15 keys) + Pink Painted Stash (1.5 sounds fair) + 56 keys. 15 * 0.9 = 13.5 + 1.5 + 56 = 71. Buds were 16 keys at the time. 71 / 16 = 4.4

http://backpack.tf/profiles/76561198038321851?time=1402210800 - Buyers backpack before the trade happened.

Sale #4 - http://www.tf2outpost.com/trade/21067130 - It helps when it says what it sold for. Sold for a Beams Jeepcap + Stormy Mirror + 5 keys. Mini for Jeepcap below. Rest of pricing will also be below.

Sale #5 - http://www.tf2outpost.com/trade/20945243 - 1:1 with a Arcana Gentleman's Ushanka by the looks of it. Pricing will be listed below in a mini suggestion.

I can keep posting and posting proof but it keeps averaging out to the range.

Mini Suggestions for the hats above.

Beams Jeepcap:

Just like Harvest, and every other Jeepcap. Every single one of them for sale is duped. Fantastic. I will not be able to put together a suggestion for this as histories and stuff won't match and I won't probably have any proof of it being a real hat. I will have to use mid range of the current price.

3.9 * 0.9 = 3.5. - Jeepcap.

17 * 0.9 = 15.5. - Stormy Mirror.

15.5 / 18.5 = 0.8. - Mirror being put into terms of buds.

5 / 18.5 = 0.3. - Keys being put into terms of buds.

3.5 + 0.8 + 0.3 = 4.6. - Total.

Current owners:

^ Look son! Nothing but duped hats!

Mini for the Arcana Ushanka:

There is currently three in existance. Only one up for sale so I will base all my proof off it.

http://www.tf2outpost.com/trade/21146408 - Current owner's trade. (10 buds!? What!? Also another angry trader. Constant insults and such.) Either way no offers on it currently. Let's move to past owners.

http://www.tf2outpost.com/user/223448,1 - Previous owner of the guy who traded it for the Stash. There was no opened trade for it. I'm going to say it sold for a Vivid Plasma Armored Authority + Haunted Ghosts Dread Knot based on the history of both hats saying they seemed to swap owners.

http://backpack.tf/profiles/76561198061913319?time=1404370800 - Owners backpack before the trade happened.

http://backpack.tf/profiles/76561198061913319?time=1404457200 - Owners backpack after the trade happened.

3.5 * 0.9 = 3.15. Rounding to 3.2. 1.15 * 0.9 = 1. 3.2 + 1 = 4.2.

I'm going to put the tradr above with the Ushanka as a outlier. New effects have such messed up sale history and are impossible to track. It would also mess up the range of the hat..

Well either way I hope this was a strong enough suggestion to hopefully get this to pass. It took me forever to do this as my original one was lost since shift + tab decided to crash right before I was done. Any feedback is appreciated, and please don't be negative if there is an issue, I can always re-suggest it.
