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

Checked. Only other sake was an outlier.

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

Checked. Robo-effect.

- 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.

It's been 26 days. I know it's short of 4 days to 1 month, but mods can leave this up for 4 days if they want to, to see if the other one on the market will be sold within these 4 days, which I doubt.
