A lot of the "rarity" with baseball cards was that they weren't inherently rare on release, but that the player on the card became a standout for the team afterwards, and therefore, owning the "rookie" card for them (when they were relatively unknown) was a game of patience and luck. Also, baseball has a avid fanbase that is focused on statistics, and the back of the cards would have the player's stats. I don't doubt that the statistics were available in published manuals back then, but having them on a card made straight comparisons across players easier than flipping across multiple pages.
