Oscars - How Many?

Steven Spielberg bought Oscars belonging to Clark Gable for It Happened One Night, and Betty Davis for Jezebel and Dangerous. Kevin Spacey did the same when he bought George Stull's 1946 Oscar for Best Score for Anchors Away in 2001. So, how many Oscars does the Academy have in its position? It declined to say. Twenty statuettes are on display at the Academy Museum in LA - although several of these are borrowed.
