In 1903, the first modern World Series was held between Pittsburg and Boston. The best of nine series was held at the Huntington Ave Grounds in Boston and Exposition Park in Allegheny, Pennsylvania. With both grounds unable to sufficiently accommodate the massive crowds, many spectators were put in the outfields themselves behind simple rope partitions and made the fields considerably smaller. The smaller fields at the 1903 World Series necessitated a slight change in rules where now a batter would get an automatic three-base-hit if the ball was to run under the rope and into the crowd. This 1903 half eagle may well have been in attendance for one of the games in the series that saw the Boston Americans overcome the Pittsburgh Pirates five games to three.
