Golden Frying Pan

The most expensive weapon in Team Fortress 2. This weapon, as the name implies, is a golden version of the Frying Pan. Any enemy you kill with the pan will become gold statues instead of scattered body parts (or gibs) or ragdolls. According to the official Team Fortress 2 Wiki, the only way to obtain a Golden Frying Pan is a very rare drop received for completing an Advanced or Expert Tour of Duty in Mann Up mode. If you receive the golden pan drop, the game will display a message alert saying "(user) just received a Golden Frying Pan!"

According to backpack.tf, the golden pan is worth 1620-1780 keys, or $3153 to $3860. If you do receive it, just get ready for scammers or random people to add you for trades...
