At the moment, I have only one major item from Harry Potter and The Chamber of Secrets.   Misha is holding one of the four Tom Riddle diaries that were used on-screen in the movie.  I believe that this is the third of the four diaries used, from what I have been able to find out.  If so, it was the diary that was used in The Chamber of Secrets before Harry stabbed it with the Basilisk fang.  It has moldy pages from being wet, and has a tiny bit of black fountain ink on a couple of spots, but no other writing.  Frankly, it's falling apart because it got so waterlogged.  But that doesn't make it any less of a treasure!

Below are autographed movie scripts of Harry Potter and The Chamber of Secrets, and Harry Potter and The Sorceror's Stone.
