Exception 2: Rare Hats

Any hat can be priced based on a single sale if ALL these criteria are met:

- There are no other recent sales in the last 3 months

- The effect is not a summer 2013 effect. (robo, 2013 halloween effects can be used as they are often rarely traded and rarely unboxed)

- The hat went to a collector or person who intends to keep the hat. A collector can be identified by looking at the person's trade history, item history of similar unusuals in the backpack OR if the owner has not resold the hat 1 month after the sale occurred.

The first 2 criteria were met. However, I'm not so sure about the last one. The guy who just bought it might put it for sale within 1 month or so. It might be best to wait for a month or so to see if he really puts it up for sale or not.
