Hello, 
I'd like to start collecting World Series baseballs (1978-today) with signatures and could use a little input on the goal I should set.  I expect to fill the collection with online purchases and attending autograph shows over several years.  I'm a big fan of homogeneous collections, so I want the same auto theme for each year.  I'd like the collection to be achievable while also holding some value over the long term.
Here are the options I'm contemplating:
- Official WS ball with auto of series MVP
- Official WS ball with auto of one of the HOFers on the winning team (MVP, where applicable)
- Official WS ball with autos of as many players on winning that I can get (I highly doubt I'd get the full roster for each year)
Which approach would you take?  Are there others I should consider?
