Reopened this suggestion because lower range did not make sense. Sorry

Bought my Nobles for 27 keys and sold it for 29 keys.

Here is the trade i bought it from:

http://www.tf2outpost.com/trade/10688669 (Vaas Montegro sold it to me, because there are a lot of offers on there)

Here is where i sold it:

http://www.tf2outpost.com/trade/11168846 Had the trade up for a couple of days before it was sold...

Other evidence:

(If there is minimal evidence, it is because all the other trades have a b/o of 3 buds)

Offers:

1 bud + 10 keys (1.42 keys)

Here is his nobles --> http://www.tf2outpost.com/trade/11217199

Hope this is sufficient.
