Sale #3 :

Sold for a duped Stormy Storm Modest (28) + 1 key : http://backpack.tf/profiles/76561198192382183#!/compare/1469232000/1470268800 (he spent the key on something, as it seems)

Value of the sale is 29 keys, outlier. (I got offered 35 pure twice on the duped Modest, both were collecting, but I don't have any proof, anyways, would be 37 keys, so in range, wouldn't change much.)

Couldn't find any other sales. Not sure, if I should go with 35-45 or rather 45, since it was a pure sale. Last suggestion had a identical situation and the suggester took the 36 keys in unusuals sale for it's low-end, so I guess I'll go with 35-45. If there's a need to resuggest, I'll do that after someone points out the error. Thanks
