This makes my medic look Amish. I love that.

UNSOLDS WITHIN THE CURRENT RANGE

http://www.tf2outpost.com/trade/15312984 - 5.77

http://www.tf2outpost.com/trade/15370523 - 6.00

http://www.tf2outpost.com/trade/15484080 - 6.00 (Young, though.)

http://www.tf2outpost.com/trade/15489069 - 6.00 (I think?)

The reason that I have so little unsolds is because a lot are still trying to sell for a key (which is slightly pathetic), or they're special (painted/level #/craft#/etc.) However, since I cannot definitively prove that 6 ref isn't possible, that'll stay in the range for now. However, with the availability of them at 5.33, I think that this is a nice conservative range.

Any proof that can support/debunk my suggestion is welcome! :)
