Brian Crecente explains arcade economics and why video game enthusiasts lobbied for a coin dollar:

It all came down to the quarter [video game expert Mark] Cerny said. Arcade games had to squeeze enough money out of people to be worthwhile for arcade owners and game makers. But they also had to deliver enough play time to make it worth while for gamers to drop in their money. ... What remains today, Cerny says, is Japan as the single shelter for arcade gaming. And that boils down to their 100 Yen coin.
