Mark TDepends how much money you are talking about. You can get very nice rare cards if you have $50,000 to $100,000. If you are just looking for an investment with a few thousand $ then its up in the air because no one knows just what cards or signed balls will be worth in 20 years. Watch out for the signed balls, make sure they are legit.
I would say go for a set you like, the way it looks or the rare cards. If you like portrait cards then M116 Sporting Life cards are all portrait. If you like action then the Caramels show a lot of action shots. Don't look at it as an investment, try and get cards YOU like and hold them.
Goodluck..
