What is the value of a baseball autographed by the 1969 Houston Astros?
According to the collector’s price guide “Team Baseballs,” your ball is worth between $75-100, with value being greater or lower depending on players present – in particular, the inclusion of Hall of Famer Joe Morgan – plus the all-important overall condition of the ball and autographs. Other key factors include type of ball (is it an “Official National League” ball?), whether there are any “clubhouse signatures” (autographs signed by ballboys, attendants, etc), and number of signatures present. These factors, plus the authenticity of the significant signatures are the main variables in determining value.
