Sold for 34 pure.

Additional by the King:

The 47 sale buyer relisted it at 40:

Other sale: Sold for stuff that should support 47, but then dumped on scrap.tf for like half of that amount:

https://backpack.tf/profiles/76561198823739367#!/compare/1550016000/1550188800

Also unsold at 40 (9 days) and 45 (2 months). So 47 will indeed be high. 33-34 should work.

Sales: 33, 47 and 34. Classies: https://i.imgur.com/l9gZ4Iq.png. 33-34.
