Can you include a comparison to show the amount exchanged, or a picture of the accepted trade offer?

Edit: There is also one for sale below your buyout

You need to use compare links, sending an item history alone isn't considered valid proof of a sale.

Here u go:

https://backpack.tf/profiles/76561198183931751#!/compare/1635897600/1636070400

It was previously sold for 135 keys:

https://backpack.tf/profiles/76561198148511293#!/compare/1628726400/1628812800

Also there's a seller at 140 keys for 3 months: https://backpack.tf/item/1649004522

The one you bought is spelled, so given the unsold your sale will most likely be an outlier

Current price is based on the spelled version (like 170) but there's a non-spelled unsold at 140.

Best to wait for the 140 one to sell. You can close this.
