A few months ago, I had purchased this off the steam market. This link will show you a video of the photo I took: http://www.youtube.com/watch?v=UPTh__DzHCQ. Sorry if I am causing any inconvenience. I purchased it for $70 off the market. Keys have a value of $2.50. That values it at 28 keys. But, $70 dollars is the equivalent of 33 keys on backpack.tf. That being said, the highs and lows have been determined. Actually, 33 keys = $69.57, so it's about $70.
