Philosophers Stone holds the sets from the first Harry Potter film, released in the United States as Harry Potter and the Sorcerer's Stone. The first wave came in 2001, the same year as the film, and was LEGO's first look at the Wizarding World, with 4709 Hogwarts Castle, the Hogwarts Express, Hagrid's hut and the trapdoor challenges that guard the stone. Those first figures had yellow faces, as LEGO's licensed figures did until 2004.
Philosopher's Stone currently consists of 28 sets that as of now has run from 2001 to 2025. As of today,
76435 Hogwarts Castle The Great Hall is the most valuable Philosopher's Stone set with an estimated new/factory sealed value of $469.
