The Noble Collection is a large producer of Harry Potter merchandise, such as replicas of wands and broomsticks, pewter statues, and other Harry Potter based items (including a very detailed replica of the Philosopher's Stone). Other items in the collection include Lucius Malfoy's walking stick, Hermione Granger's Time-Turner, The Marauder's Map, a Wizard's Chess set and the Nimbus 2001 and Firebolt brooms. They produced the Gringotts Currency set and, from that, the sizes of the coins compared to U.S. coins were compared and established.
