I personally would not, although I think it's a great idea. Usually, tokens tend to cost too much, whereas you could just use a simple 25 cent coin. This way, lets say you have some people who play, they wont mind putting in a few quarters to play some games, why would they? Quarters have a value, tokens do not. Therefore, unless you plan on putting a machine in the public, there is no reason to spend the extra $50 to buy 200 tokens that have one purpose for one machine.
