Mark Cooper's book Baseball Games 1995, has a picture of the game board, and a picture of the game you have but dated 1913. It is 13" x 13", he writes that a larger version 18" x 18" was also made, that is the game you have. $150 -$300 for the 1913 version.
He writes that the discs are exceedingly rare.
The game board also came with the game, 18" x 9". A 3 dice game board with metal rimmed discs. The game board is price at $50 - $100.
Hope this helps.
