"Then there are two things I should give you." Dumbledore pulled a small golden key out of his pocket. "The first is the key to vault 687 at Gringotts Wizarding Bank. It is a trust vault set up by your parents, and should contain more than enough money to see you through your school years. On your seventeenth birthday, when you come of age in the wizarding world, keys for the Potter family vaults will appear within it. Be careful with this key—whoever holds it has the right to withdraw as much money as they wish."
