Resuggestioning with one more proof:

Im trying to fix a first value.

I had bought one for 23 keys + 1 ref: http://www.tf2outpost.com/trade/16116905 .

No doubt that was a quicksell.

Then i were collecting offers which concentrated around 2 buds.

At least i sold it for 1 bud + 21 keys pure: http://www.tf2outpost.com/trade/16233435 .

It was just 1 of 2 on the market, which was only 2 times sold in the last 6 month.

The other one on the market was sold for a circling heart Tippler's Tricorne to мт | Graba without a trading page for proof.

Its not a lot of proof, but to fix a first value it should be enough.
