Collector's are new. You know what happens to all new things *cough* taunts *cough*. This is a very good suggestion because from me just browsing outpost and backpack.tf listings collectors barely get sold for their upper range. Lots of people have the common sense (like with the current situation with keys) not to buy it if they are likely to drop. If you want evidence you might have to give me a while because i'm a bit busy now, but i would be more than happy to collect some when i get the chance. :)
