Rarity:

12 in the wild, 2 for sale on OP atm.

NOTE: All prices will be based on the USD value of unusual hats from backpack.tf's database and $33/bud and $1.30/key. Due to the completely inaccurate backpack.tf cash prices of buds (~$38.7) and keys (~1.4) all my PC's will be in USD so that the database will store reasonable cash values for the hats. Until the website is altered, ppl will just have to deal with the silly exchange rates :(

Allowing voting on the cash price of buds and keys will correct the unusual pricing problems on backpack.tf
