How much is the milton bradley game WIN A CARD board game worth?

I have never heard of the game but I did find it referenced at Boardgame Geek. As with all collectibles, the value depends on demand, rarity, and condition of item. As a collector, the missing cards makes of no value to me. Other collectors might offer you a few bucks but if you have your eyes on making the down payment on a Bugatti then this game will not cover it.
