My Proof:

Buyer:

http://www.tf2outpost.com/trade/18151339 - Mass 1.4 buyer

Sales at 1.6 keys:

http://www.tf2outpost.com/trade/18275455 - Less than 20 hours

http://www.tf2outpost.com/trade/18279223 - 5 hours

http://www.tf2outpost.com/trade/18281601 - Less than 4 hours

http://www.tf2outpost.com/trade/18058464 - 1.7 keys

http://www.tf2outpost.com/trade/18263213 - Less than a day, 1.7 keys

http://www.tf2outpost.com/trade/18276761 - 16 hours, 1.7 keys

http://www.tf2outpost.com/trade/18288475 - 2 hours, 1.7 keys

http://www.tf2outpost.com/trade/18184868 - Less than 7 hours, 1.85 keys

About 90% of the market is either killstreaks, parts, austrlaium or in sets, which makes almost nothing really valid

About all sales at more than 1.6, those exist as much as below 1.6 exist

When I wrote this comments and when I first made the suggestion I saw some at 1.6 and below that in Classifieds

I was wondering if 1.7 should be worth including because there are recent fast sales at it

What guided me was the fact that 1.6 is the most commonly traded price right now and above or below that is quite even

If there will be MANY sales above 1.6 I will re-suggest but more are needed in my opinion to include anything higher

Thanks for the support though, anything that indicates a bump helps

A tiny bit of extra proof:

http://www.tf2outpost.com/trade/18297801 - Sold for 2 keys in 1 hour
