Harry's parents left behind a somewhat large pile of wizard's gold, used as currency in the world of magic, in a vault in the wizarding bank, Gringotts. After Sirius' death later in the series, all of his remaining possessions are also passed along to Harry, including Number Twelve, Grimmauld Place, and Sirius's vast amount of gold were transferred into Harry's account at Gringotts. Rowling noted that "Harry's money never really is that important in the books, except that he can afford his books and uniforms and so on.
Among the school items Harry purchases in Diagon Alley after discovering his gold inheritance is his first wand, an 11-inch-long holly and phoenix feather model that he learns is the twin of Voldemort's wand, as the feathers that both wands contain as their cores both comes from Fawkes, the phoenix that Dumbledore keeps as a pet in his office until his death in Half-Blood Prince.Harry's wand is broken in Deathly Hallows. For a time, he borrows Hermione's wand, and later steals Draco's. With his defeat of Voldemort at the end of the series, he comes into the possession of the Elder Wand, but uses it only to repair his holly wand, before returning it to Dumbledore's tomb, from which Voldemort had stolen it. In the film version of Deathly Hallows Part 2, Harry destroys the Elder Wand.
Harry also inherits indirectly two of his father's prized possessions. One is the Marauder's Map, given to him by interim owners Fred and George Weasley, which endows Harry with comprehensive knowledge of Hogwarts' facilities, grounds, and occupants. The other is his father's Invisibility Cloak, given to him by Dumbledore, which eventually proves Harry's descent from the Peverell family. Harry uses these tools both to aid in excursions at school and to protect those he cares about; the Invisibility Cloak, in particular, can hide two full-grown people. If three fully-grown people hide under the cloak their feet will be visible. When Harry reaches his age of maturity at seventeen, Molly Weasley gives him a pocket watch which had once belonged to her brother Fabian Prewett, as it is traditional to give a boy a watch when he turns seventeen.
Throughout the majority of the books, Harry also has a pet owl named Hedwig, used to deliver and receive messages and packages. Hedwig is killed in the seventh book, about which Rowling says: "The loss of Hedwig represented a loss of innocence and security. She has been almost like a cuddly toy to Harry at times. I know that death upset a lot of people!" As a Quidditch player, Harry has owned two high-quality brooms. The first, a Nimbus Two Thousand, was procured for him by Professor Minerva Mcgonagall when Harry was added to Gryffindor's Quidditch team despite being a first-year student. This broom was destroyed by the Whomping Willow during a match in Harry's third year. It was replaced by a Firebolt, an even faster (and more expensive) broom, purchased for Harry by Sirius; however, as Sirius was believed to be trying to murder Harry at the time, the broom was subjected to stringent security inspections before Harry was allowed to ride it. Harry used it throughout his Hogwarts career until it, along with Hedwig, was lost during the July escape from Privet Drive in the final book.
Harry also owns a mokeskin pouch, or small 'bag' that is used for storing items, which no one but the owner can get out. He receives this from Hagrid as a 17th birthday present. Harry uses the pouch throughout the course of Deathly Hallows to keep several sentimental (yet, as he himself admits, otherwise worthless) objects such as the Marauder's Map, a shard of the magical mirror given to him by his god-father Sirius, the fake Horcrux locket that had belonged to Sirius's brother R.A.B (Regulus Arcturus Black), the Snitch bequeathed to him by Dumbledore, containing the Resurrection Stone that had previously been set into Voldemort's grandfather Marvolo Gaunt's signet ring, which Harry discovers is actually the second Hallow, a letter from his mother to Sirius with part of a photo (of him and his father, James), and eventually, his own broken wand (which Harry later repairs with the Elder Wand).
