Where is the goblin token found in Lego Harry Potter?

You're likely thinking of the Goblin Bank Token, which is not actually a token but a key item in the Lego Harry Potter: Years 5-7 game.

Here's where you can find it:

* Gringotts Wizarding Bank: It's inside Gringotts, the goblin bank in Diagon Alley.

* Inside the Vault: You'll need to find the vault with the dragon on top.

* Behind the Dragon: The Goblin Bank Token is hidden behind the dragon statue.

Note: This isn't a typical collectible token like the ones you find for completing challenges. This key item is necessary to open a secret room in the bank, where you can get some extra gold and unlock another character.
