If you can't infer from posts, my vote would be pass.

If you really want an old time game used ball, I'd get one with exceptional and iron clad provenance, such as from a player's estate. There also are trophy balls-- painted up or signed by the team--, that were usually used in the game. Though provenance for these still is important. They can be found (follow the big auctions and respected dealers) and exist for both baseballs and footballs.
