Sovereign 460, Factory 25 back. Another of the more desirable players in the T206 issue who are not in the Hall of Fame, Chick Gandil's involvement with the Black Sox scandal make his cards widely desirable among collectors today. In this case, the Sovereign 460 is one of the more difficult backs in which Gandil's cards can be found (the toughest confirmed back is the Red Hindu), a level of scarcity that adds considerably to the desirability of the card.
