Unpriced hats – hats that have never had a proper suggestion or have no price

Two sales are required to establish a range on unpriced hats. If the two sales are discrepant, a third sale is required to determine the outlier. .

Exception 1: High Tier Hats

Sales for high tier hats (>200 keys) can be based on a single sale if there are no other sales in the last 3 months. Estimations can be made for unpriced / outdated parts of that trade as long as reasonable estimations are provided.

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 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.

Obviously, this is not a high tier hat, so we can't use Exception 1.

Looking at exception 2, this hat (according to Cobalt) has not had another sale in the last 3 months. Furthermore, the sale occurred on April 15th (according to Pot history), which is well more than 1 month after the sale has occurred. This hat can be priced using only 1 sale.
