Gold Mine

Game was available as either a single coin game or, for ten dollars more, came with the "Plus 4" coin feature, allowing a choice of pricing at 5, 10, 15, or 20 cents per game with just one coin chute. The Cash Box article in this listing explains that each additional coin gave the player a better chance to win by lowering the high score needed to win an award.
