2 usable sales, one of which has happened literally five minutes ago.

Sale 1

I sold it + a white strange siberian sweater for 50 keys.

50 - ~1.3 (valuing keys @ 18.44 ref and the sweater at 1.3 keys, item price + 50% paint price) = 48.7, rounding to 49.

Sale 2

I bought it for a clean Purple Energy Tough Guy's Toque (very recently updated at between 40 and 45, valuing at its mid-range price which is 42.5) + 15 keys.

Rounding to 57. Proof below.

1 unusable sale which includes a hellfire robo stuntman. Obviously an outlier compared to the other sales and taking into consideration the other seller's lack of experience (he unboxed it - http://www.tf2outpost.com/trade/27717243 - warned him)
