I bought a Flies Reggaelator for 11 keys. I accidentally put the wrong price into the suggestion which submitted it in my past suggestions so please don't assume I'm spamming suggestions :)

This hat is Duped but from what a Mod here on Backpack.tf said. https://forums.backpack.tf/topic/6033-rules-for-unusual-price-suggestions/?tab=comments#comment-167485 duped is considered equivalent to clean at values below 30 keys.

I can't find a Flies Reggaelator on Backpack Classifieds, Outpost, Scrap.tf, Bazaar or Marketplace.tf. There is a Flies Reggaelator on Steam Market for $29.90 which would be around 13 - 14 keys but no one has seemed to have bought it yet.
