Countering the suggestion that just got accepted. The veil I recently sold was not strange when I sold it: http://www.tf2outpost.com/user/76561198096389539?itemid=4191439179

I had difficulties to sell it and eventually had to accept a Max Head offer.

So, re-doing it:

Sale 1 (credits to Happy Dank Derp) Sold for S kS Aussie Sniper Rifle + 3 Keys

Taking the max as pure, so, a sale at 28 keys.

Hence the range, 28 - 32 keys.
