"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 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." (1 week left but not on OP nor classifieds)
