I use The Trading Card Database to verify rookie card status.
Let me know if you need any of these to complete your collection.
Send an email message to BigBubbo@yahoo.com about any cards you wish to purchase or talk trade. I personally collect Bob Gibson, Roberto Clemente, St. Louis Cardinals, Cleveland Indians, and Kansas City Royals.
