What brand of baseball cards has the most value?

Answer 1

Check out this source. http://www.helium.com/items/462311-assessing-the-value-of-Baseball-cards I can't really tell you exactly which cards are worth alot, but any well known player's rookie card is usually worth something. Also the really really expensive ones are the vintage baseball cards which were sold with tobacco products when baseball was originally developed.

Answer 2

I believe Goudey or one of the old ones, maybe Play Ball.
