Only 2 pages of this on outpost and people are quickselling it for 0.66 ref or 0.77 ref but i'm not going to add it as proof

Unsold for 1.33 ref or less:

http://www.tf2outpost.com/trade/13721110 1 day hardly bump

http://www.tf2outpost.com/trade/13571722 1 week

http://www.tf2outpost.com/trade/13628408 1.22 4 days

http://www.tf2outpost.com/trade/13724014 Never bump 1.11 ref

Sellers selling it for 1 ref:

http://www.tf2outpost.com/trade/13752642 Selling it for a genuine ham which is 1 ref or 1 ref

Conclusion: It's hard to sell it for 1.33, 1.22, and 1.11 ref and it can take days or weeks to sell one above 1 refine metal. Even though I have no trades of someone that sold one for 1 ref but I hope you get my point.

Extra proof would be nice.
