Only keys match, but the seller says it sold for 45 keys + Stattrak MW AWP Redline (mini at 17) + "sweets"

http://www.tf2outpost.com/trade/28381069 ----- B/O was 70 keys, sale is confirmed here.

----------------------------------------------

Mini for the AWP: Sales around ~$44, which is 16-18 keys. Taking 17.

I assume the sweets were a minor part of the deal, so i will just consider the keys + AWP

=======> 45 + 17 = 62 keys
