http://tf2tp.com/trade.php?trade=9274691 - 5 keys + 1 ref ongoing trade

Hard to get you proof of successful trades cause they get closed on outpost. But if I can find this many, then surely there are plenty that I have missed. I think this may deserve a price range of 5.5-6 keys. But I'm sure Mr. Bucket can give better input since it seems like he's been trying to sell his one for a while at 6."

"6 flat seems kind of high when you can still find 5 key sellers occasionally
