The Yoke (if it works properly) is probably worth $150 to $170. Coin door (if it works) is probably worth $20 to $25. The cabinet (if in good shape) is probably worth $25 to $40. If the monitor works, you probably could cover the rest of the cost.
I guess it depends on what you plan on doing with the cabinet, how much you like the game, whether you plan on selling parts of the game, etc....
