This suggestion has made my head hurt, and I’m sick of looking through trades from a month ago to find the one in ten that was recent. I could only find one sold within the last two weeks for 0.22:

This is definitely not a low end price, the volume of trade is simply not high enough. 0.33 is definitely the most common price, and that is where the majority of traders operate:

http://www.tf2outpost.com/trade/6723627 - Sold for 0.33

http://www.tf2outpost.com/trade/6426220 - Sold for 0.33

http://www.tf2outpost.com/trade/6640453 - Sold for 0.33

http://www.tf2outpost.com/trade/6367023 - Sold for 0.33

http://www.tf2outpost.com/trade/6272774 - Sold for 0.33

It is possible to sell for higher, but after considering it, I believe that the volume of trade is too small on either end to warrant a range. Sure, one went through for 0.22 and 0.44 respectively – but the commonly accepted price is most definitely 0.33, although I think an upwards trend might develop. Watch this space.
