Typical Collection Size?

Of course I know that the type of paper money you collect will impact the size of your collection. If you only collect U.S. Gold Certificates or Treasury notes you won't have a lot of notes, but you will need a lot of money to acquire your notes. I read that Dr. Albert Pick had over 180,000 notes in his personal collection (mostly notgeld). i would guess that his collection was probably close to, if not a record size. Any thoughts on what is considered a small, medium or large size collection of paper money. Feel free to define paper money any way you want (including U.S. or foreign notes, MPCs, emergency currency, movie prop notes, depression scrip, etc).
