Don't even have to do that, to be honest.<br/><br/>"Hey, how much for this?"<br/><br/>"It's three fifty (3,50)."<br/><br/>I think as long as we model after a currency that isn't too far from what we know, we'll be fine without naming a specific currency. That means that prices we name should likely be akin to Euro and Dollars, which both deal with cents and wholes (by which I mean whole Dollars and Euros). Yen, meanwhile, is always Yen and doesn't do with cents and such, making it a more unfamiliar type of currency for most of us to deal with.
