I read, but still i am sure that it belongs to Godric Griffindork.
Watch the movie over again and you will know. Because Dumbledor explained to harry, and never mentioned it was mine!
It's fairly well known that no movie can relate what the book say in any series. So that point is moot in any debate.
And I also said yes, it did once belong to Godric Gryffindor, then it was passed down to his successor, and so on, and so forth. All the way down to Dumbledore. So yeah. It does belong to Dumbledore.
