I see you are new around here in suggesting prices, but when you are suggesting you need to find some proof. Proof means links from TF2Outpost.com trades (in this case sales you need) or Backpack.tf classifields. When you are raising an item, you need to prove us, that there are sales at higher. You can find sales, by bookmarking existing sellers that sells at higher right here http://prntscr.com/878czk and after a week you can look at your bookmarked trades and see if it sold http://prntscr.com/878d9n then you can make suggestion, put the sales, links in your suggestion. Try looking at past accepted suggestions to see how to format the suggestion. :)
