Hi Koda, re: large autograph collection.  Go into the Forum tab and go to Town Square and create a discussion (click the Add+ button to start yourself out).  You'll get more answers that way.  If you can tell what type of autographs you have that will also help (ie sports, movies, music, etc.,) it does make a difference, as different places sell different types of autographs.  People here may be willing to buy some of them as well if you can part them out in pieces as not everyone has the same "tastes" as others.  

Hope this helps.
