backpack.tf is pricing the robo hats at 1.5 ref
they'll probably drop to that eventually, but they probably aren't going for that now.
Backpack.tf has lost alot pf its credibility IMO. The voting system is good on paper but it just doesn't seem to work well. You don't need to look at the proof to vote, so if alot of people want it cheaper/more expensive they just vote it up or down without caring about the evidence. Even then the admins don't have to accept the suggestion based on votes, (which solves some problems but creates others). In the end all it is is tf2 spreadsheet all over again, a few people manipulating the market to thier needs.
It is still marginally better than spreadsheet though, at least it gives the community somewhat of a voice.
