How much is a 1989 American League All-Star team autographed bat worth that is signed by Mark McGwire Bo Jackson Cal Ripken Nolan Ryan etc?
Your bat would be worth slightly more than a similar team-signed ball, and according to the collector's price guide, "Team Baseballs," a ball is worth between $250-350, with value being greater or lower depending on exact players present - plus the all-important overall condition of the bat and autographs. Other key factors include type of bat (is it game-used?), whether there are any "clubhouse signatures" (autographs signed by ballboys, attendants, etc), and number of signatures present. Whether it documents the American or National Leagues rosters, or a combination of both is also important. These factors, plus the authenticity of the all the significant signatures are the main variables in determining value.
