Selling doesn't mean it has sold. Try checking the history of the items to find solds or at least find offers. For example:

http://www.tf2outpost.com/trade/13984979 - Sold for an Antifreeze Capo (5.7 buds)

http://www.tf2outpost.com/trade/13315291 - Offer of a level 100 Disco Beat Down Snaggle (no price set).

I would say that this price is fine as it seems you quicksold yours as it took less than a week. http://www.tf2outpost.com/trade/14018632

one sale isnt enough proof, try to get more sale proofs and not offers and b/o's

what did you buy yours for?

Everything is selling for lower right now while everyone is quickselling/buying. To take the performance from the last two weeks and use it as the basis for the price, would drive the price of many accepted hats down 1-2 buds.

I have one of these dragonborns, traded an unusual worth over 6 for it during the time when both were unpriced (about 2 weeks ago). (roboactive master's yellow belt)

This would be a sale at 4.5 - http://www.tf2outpost.com/trade/13984979 - sold for antifreeze capo

Price here is outdated, but both the current and previous owner had b/o's of 5, so this would be 4.5 after overpay

But this one sold for 5 - http://www.tf2outpost.com/trade/13315291

I'd say a range of 4.2-5 would be more accurate. Would also cover the uncertainty of the value on that capo trade

Link one now lowered his b/o to 4.5

SO we have two on the market that would accept ~4.5 I think its fine
